4L60E trans. pan bolt torque specs

========= ========= snipped-for-privacy@zoemail.net (DonW)

Need torque specs for '03 Envoy transmission pan bolts using new gasket.

Did my annual "drain the pan & new filter" routine and discovered I didn't have the correct specs to reinstall the pan. TIA

=============== ===============

TorqueSpecs: good-n-tight

I personally use a 3/8 impact gun with a 4" extension.....it's tight when the socket and extension rattles.

WARNING........ my 3/8 impact is worn out......adjust yours accordingly.

but seriously folks....... you could do it this way too.....

use a ratchet with a 6 inch extension, tighten the pan bolts up to "snug"......then using only one hand on the ratchet, tighten the pan bolts up tight. Then.....using the other hand hit each bolt one more time with jest a little nudge.

actually works faster than it sounds.

Fact.....not Fiction

MarshMonster ~tightens 4 or 5 a day that way~ ========== ==========

I always torque mine to 14 Ft/Lbs. That is about the correct amount based on the bolt size and hardness. You could go a little more but the important thing is that they are all the same torque and not to squeeze out the gasket.

//Hunter

12-15 ft/lbs

Doc

Thanks for replies. I initially torqued to 10 ft-lbs. I'll drive for awhile and recheck. While the pan was off it's now sporting a new drain plug to make next year's job a little smoother.

Good idea, installing a plug. Details please. H

don't go more than 15ft/lbs at the most... it's not the bolt you need to worry about.. it's the aluminum the housing is made from.

-Bret

The plug is a 1/2-13 nut & bolt. While the pan was off I drilled a 1/2 in. hole & tack welded (I've got a small mig welder) a nut to the inside of the pan. The nut has a couple hacksaw slots about 1/3rd of the way so oil can drain from the bottom and not stop at a level the thickness of the nut. The nut is tightened in place and tack welded on sides opposite the saw slots. I use a hardware store copper washer as the actual seal. I've done this on a couple vehicles. Just have to look at the bottom of the trans. to make sure the location of the drain will not interfere with anything. Most auto parts stores sell a drain kit that is tightened in place and has a 1/8 in. pipe plug as the actual drain. While they are ok some residual oil will remain in the pan.

Same ole question.......

How you gonna change the filter? Yank it out through the drain hole?

Summit Racing, B&M, or any trans parts house will sell you a drain plug kit for around $8.00. Pop a hole in the pan and stick her on in there.

No welding involved.

Though you may still have that residual left in the pan.....you know.....bout a half a coffee cup full. But not to worry......you can just wipe that out with a rag....... WHEN YOU TAKE THE PAN OFF TO CHANGE THE FILTER.

after all......that's why you do a service any ways .....ain't it??????????????

hmmmmmm......maybe i've been wasting my money all these years....changing the oil filter when i done all them oil changes.

nah....

~:~ MarshMonster ~has a service to do.....now where's that impact gun?~ ============== ==============

Nope. But I don't trust transmission flushes. AFTER I change the filter, I like to drain the pan a couple of times over a period of a few weeks to get more of the old fluid replaced. That's much more easily done with a plug installed. Makes filter changes much less messy, too for those of us that don't have a lift to put the vehicle on. H

Read original post.

=========== =========== snipped-for-privacy@zoemail.net (DonW) slapped ole Marsh in the face with his greasy shop towel and repremanded him with..........

Read original post.

============ ============ Marsh grabbed a fender cover, wiped his head down, and appologized (sorta) with:

I stand corrected. Forgive my impetuous reply. I promise to do better. I will read all OPs twice before posting. I will read the thread twice also. I WILL READ WHAT YOU TYPED.

and then reply.....i promise!

AND THEN I WILL READ BETWEEN THE LINES AND ASS U ME that you meant WHAT YOU DIDN'T TYPE!!!!!!!

After reading your OP again, then your next reply.......

I G U E S S E D ......that you're probly gonna change the filter during your services.

after all...... you didn't come right out and say it.

So..... if you ever come into the shop for a tuneup..... i'll go ahead and assume that you want me to install the whole ball of wax.....

that way i'll be covered......and you'll be happy.

MarshMonster ~would like you to read what you typed, and then maybe type what you meant~ ============ ============

If you read my post, you'll notice that i may have made a slight mention about an easier way to put in a drain plug, and possibly, if i remember correctly, i may have made a minor reference to changing the filter after you pulled the plug.

With that said......

Yer a smart feller for not trusting tranny flushes. I don't advocate them at all. Totally against the process, for my own reasons.

any whooo...... bout draining that fluid a couple times......

why over several weeks? why a couple times?

and......

how often do you torment yerself by doing this?

and ...... could you please define "flush" for me,

jest curious

MarshMonster ~:~ =========== ===========

Also Sprach Marsh Monster :

Because you can't completely drain the torque converter just by draining the pan. A lot of fluid remains in the converter. So if you drain it several times, each time you drain it you dilute the "old" fluid by half.

You have to drive it a bit to mix the old fluid with the new before you drain it again. A few weeks isn't necessary, 10 miles or so should do.

Say 25% of the fluid remains in the transmission after draining. If you fill it up with fresh fluid, you have 75% fresh fluid, and 25% old. Drive it a bit, drain and refill. Now you have 12.5% old fluid, 87.5% new. Do that again, 6.25% old fluid, 95.75% new, and that's good enough for me.

Me, every 5 years or so, but I only put about 3 or 4 thousand miles a year on my truck. My other two cars are manuals, and get the gear oil changed every 2 years.

Take it to a transmission shop. They disconnect the lines that lead to the tranmsission cooler and hook them up to a flushing pump. It forces new fluid in, and most all the old fluid out. Eliminates the drain and refill 3x method. Most of the chain shops do NOT include changing the filter in this service.

BTW, could you please use normal quoting characters, a ">" before each line of quited text, rather than this:

It makes it really tough to figure out who said what.

We've tried to get the Marsh man to cut and paste and quote normally, but so far it hasn't worked. I will say that it's much better then it used to be when he first appeared. Once you figure out his way of putting together a post, you can sorta make heads or tails of what he's saying. I don't think I smoke what he's smoking, so that could be part of the problem.

Ian

Why??

Why would you have to guess? He stated clearly that he had changed the filter.

Sure he did. You just can't read.

Hairy ~would like Marshy to explain his sig. line.

Marsh must be smoking some really "GOOD SHIT!"

It must have cured what he didn't have, and that's why he posts the way he does?

LOL

Refinish King

Nah, he's a webbie and AFAIK WebTV doesn't put ">" in replies.

A TALKING BANANA!!!!! man that's some good shroom juice......or maybe it wuz duh smoke.

Hey Nanner,

them lines there..... how's that.....??? Better??

NO!!???

sorry.... I'll try something else next time....promise.

Now.... bout that "flush" definition you gave me....

thanks. preecy eye ate it . clears things up.

however....... what's the chances that yer wrong???

you know..... like .....maybe not completely correct??

like..... maybe yer guessing???

or.... jest passing on hear-say??

nah...... you seem like a good enough feller to me. I don't think you'de mislead the entire internet by posting false, misleading, potentially costly, information out here in space for all DIY'ers to read.

would you???

come on..... yer guess'n ain't yuh?

you don't really know fer shure what the proceedure for a tranny flush is...do yuh??

yer jest repeat'n rumors.....ain't yuh??

that's okay..... I forgive yer ignorance.

but.... you better becarefull bout that sort of thing.... it's libel to git you called names in the NG's.

oh yeah.....

i'm gonna check up on that tranny flush deal. jest in case i might be the one that's mislead'n folks.

if i was wrong bout you....i promise to make an open statement in Forum apologizing.

and...... jest fer you..... i'm gonna work on this quoting thing too. but fer now..... any thing you see under the little lines......

will be breaking the quotes between each reply.

that help yuh any??

how bout that background color?? is it okay??? some folks don't like it. but then..... some folks don't tint there eyeballs with the same chemicals i do.....so go figure.

by the way ...... i didn't ask for a definition of a tranny flush. i asked for HIS definition of "Flush". you might want to look it up yerself.

now...... would you mind answering a question for me?

during this little proceedure...... are you changing the filter EVERY time?

the understanding here is that yer doing this at least 3 times ....and you personally advocate that 10 miles between the draining is enough... correct??

3 filters 18 qts tranny fluid

that's what.....bout $55.00 ????????????

of course.....we kinda need to figure in all that aggrevation involved in actually doing it ON THE GROUND....too don't we.

you know.... that scalding hot arse fluid run'n down yer arm pits.....lmao.

hehehehehehee yer silly

and you reeeeellly think..... that doing it 3 times is doing it good???

bout that process you explained to me.....

let me see if I can figure yer logic here.

A 4L60E holds 12 qts of fluid.

now on the first service you cut that down by 1/2

so you pour in 6 qts....now you got.....

how many quarts dirty fluid is still in the tranny???? jest 6????

ROTFLMFAO.....

yer not only silly.....

yer hilarious.

MarshMonster ~wonders if you want some shroom juice too........so you can realize how funny you really are~ =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

you lazy focker you, read the thread yer own self.....dipthong!!

The only place the OP mentioned the filter wuz at the start of the thread. NOT THE ONE I REPLIED TO that you were quoting me on. Though....unlike you, i did read the entire thread.....and.....had..... READ WHAT WAS WRITTEN!!!

i will allow that he changed the filter on the initial job.

however....... catpuke.....

I F........yer sorry, quick draw'n, hip shoot'n, fast diagnose'n arse would read all posts that the OP has made.....perhaps you would READ WHAT HE WROTE!!!

or.... didn't you see the part about the bit of fluid left in the bottom of the pan???

DIPSTICK FER BRAINS!!

now Hairy....... whhhyyyy nnnnn thheeee HELLL.... would the guy be worried about a 1/2 cup of fluid in the bottom of the pan.....???

IF HE WAS CHANGING THE FILTER???!!!!

rekon he's jest overly neat there Hairy???

slow down a bit there Hairy.... no need to read so fast.....

cuz......

I TYPE REAL SLOW.

and one more thing..... bout that Hair of yers......

we're gonna have to notify the EPA ....

you got enough of dem empty spray cans lay'n about to warrant calling you a mass producer of hazardous waste.

you could get yerself a fine.

and if'n you persist on use'n so much of it.... how bout some tape on them eyes when yer spraying it on.....might help a bit in yer comprehension if'n you could actually see what you wuz try'n to.
