Which Synthetic ATF?

Your dealer should have Mopar ATF+4. Most Dodges from 2001+ require ATF+4.

Thanks for the reply, but I am looking for Synthetic. I can get Mopar +4 from Wally World 2 blocks from here.

Mopar ATF+4 is synthetic. Did not know it was sold anywhere but the dealerships. Thats good news.

Oh..I did not know it was Synthetic. The Valvoline and the Mopar do smell almost the same.

The crap they put in my trans has no odor at all, so I know it's got to be cheap that came in a cheap drum.

Thanks for that insite.

If your dodge is newer than 2000 then get that crap out QUICK! Something like Dextron, Merc etc. can cause major problems with your transmission. Mopar ATF+3 maybe ok but ATF+4 is what is recommended. Chrysler created ATF+4 and were the only ones producing it until recently when they licensed others to produce it. Look in your owners manual or on the dip stick. It probably says requires ATF+4 (might have the ATF+4 designator #9602).

Actually it is a 2000, so I am good one that, but I know that garbage they put in it is not doing the trans any good. So tomorrow I will drain it out and put the +4 in it and see how much better it will run. By the odor, I think it previously had +3 in it., but it still got burned out with that in it, and a cooler w/electric fan somehow. I hope this +4 will protect the transmisson better. Thanks for the info.

You'll most likely have to get it flushed to get all the old stuff out from the tranny, torque converter and cooler.

How does one flush it?

Most shops do it but I don't like taking mine to any except the dealer...because so many shops fail to use ATF+4 and instead use some crap and then tell you they put in an additive that makes it the same.

Basically they open the line leading to the tranny cooler and pump out the old and pump in the new. Dropping the pan will only get 1/2 or less out.

Maybe someone else here has an easy procedure to get as much as possible out.

Before you jump the gun, make sure that ATF +4 is even recommended for your trans. Just because it has a higher number does not always make it backwards compatible with the ones preceding it. This fluid has specific lubrication, flow, and friction properties for the newer DC transmissions that might not be compatible or required for your trans and using it at best might be just wasting money and at worst, could damage your trans. I would give the dealership a quick call and ask.

No need, ATF +3 is no longer manufactured and +4 replaces it.

Okay Iw ill give a few places some calls and see...thanks

Better wait for punkin's opinion.

"You are failing to understand what you posted yourself, that the grades in the OM are RECOMMENDED, that DOES NOT mean you have to use it, that does not mean you will void your warranty and it damn sure as hell does not mean you will damage your engine." - punkin

I thought you had a modified transmission with a bunch of DTT parts in it. If so you might want to talk to them before you put anything in it. Actually you might want to talk to them anyway. Here's their phone number:

And while you have them on the phone, ask them what ever happened to the massive 48RE failures we were all supposed to see by now. After all, they were designed to fail at 75,000 miles.

I remember that, good question

ATF+4 is fully compatible in dodges that require ATF+3. It was specifically designed to meet all ATF+3 specifications. Theres only a couple Dodge engines made after 1999 that do not use ATF+3 and the trucks don't have them. But I do agree to double check the owners manual.

Only a DTT torque coverter. The trans was modified by a shop, but no other DTT part in it.

The owner's manual for 2000 indicates that ATF+3 or Dextron III is suited to use. However, seeing the result of what I think was Dextron 3 or +3 in it, I think I will put +4 in it.
