Transmission wierdness

Sounds like either the lockup clutch in converter is bad or the control circuit for it is bad. The converter stalls around 2500 RPM so you will not see much if any RPM drop when 4th gear (OD) engages if lockup clutch in converter is not functioning.

I take it that is expensive to fix? :)

The converter itself is not expensive if lockup clutch is bad and can be had for under 200 bucks, the problem is that is is very labor intensive to replace it as tranny has to be removed from vehicle. If it is a control problem in tranny to ativates lockup, it should not be to expensive. Given its age and mileage thought I would tend to lean toward the converterclutch being worn out/defective.

Should I bother with replacing all the fluids then?

I will have to drive it in 3 for quite a while as I will not have the money to have it worked on for quite some time.

Thanks!!

Sounds like the fluid is way too low or something is restricting fluid flow.

I checked it last night after driving 60 miles. It was WAY too full. It measured a good inch above the full line.

It was a slight red-ish orange color. The filter and fluid and additive is cheap, so maybe I should just try it.

Fluid color is good. You could try a fluid and filter change as it will not hurt anything nor will driving it is drive/3rd gear for a while as cars came without OD for many years and they lasted a long long time.

The problem is that the 4th gear hub is stripped out. Happens all the time. If you want to confirm this drop the pan and see what kind of metal shavings are in it if any.

I replaced the oil and filter last night. There were no metal shavings at all. There was some silver sludge on the magnet, but not very much. The pan was pretty clean. The fluid smelled burnt but wasn't too bad a color.

We'll see how it goes after driving it that way for a while.

I noticed when I put the funnel on the fill tube for the transmission it created a bullhorn type effect. You could hear from inside the transmission. It sounded kind of noisy and rough. Is it supposed to sound like that? Almost like when you put a socket extension against the pulley or alternator or water pump to listen to the bearings when they are noisy.

The additive was called LubeGuard. It's in a red bottle. This is what my mechanic recommended. He uses it when there is a sticky solenoid and the customer does not want to pay to have it fixed. He said most of the time it works nicely, so we'll see.

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

Your mechanic is either an idiot, or a lier.

LubeGaurd WILL NOT....fix a "sticky solenoid".

Fact, not fiction.

Well it has fixed the solenoid. The shifting is smooth as silk. Hasn't done that for 6 months.

However the overdrive is still shot and I am going to have it rebuilt. The quote I got for a complete rebuild including updates for it from GM will be $1700 including labor and tax. Does that sound about right?

PS This mechanic is one of the best around. Great reputation and always busy because nobody goes to the other 3 mechanic when this guy does SO much better. I trust him 110%

I change my mind,

it's not yer mechanic,

it's you that's either the idiot or a lier.

You really show how stupid you are when you post like that. If you actually had a clue about mechanics you would have offered the proper advice instead of bashing someone you don't know.

Bye bye.

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

yeah, i've heard that before.

proper advice? sorry, thought i gave some. (in my own little way)

bashing? sorry, I wasn't try'n to bash. I was try'n to point out the obvious.

a clue about mechanics? ok, you may have me on that one. I concede.
