Auto Tranny question

[:I]

Howdy ya'll,

I just had my '03 Lt Ed, automatic transmission fully flushed, changed filter, and refilled with Amsoil 100% synthetic tranny fluid. Noticed I now have a strong downshift when almost coming to a full stop. Didn't notice much of one before.

I decided to disconnect the negative cable on the battery for a couple minutes to reset, and relearn. Don't know if that will matter with the performance of the tranny though.

Whaddya think? Sound OK to you?

Other than that, it seems to shift a little nicer, quicker than before, less hesitation, might be my imagination, It could be I'm looking for it to make some kinda difference to justify the $170.00 bill!

(I had it done at 40,000 mi, I bought the car with 32,500 mi on it already, and just wasn't sure the 30,000 mi recommended maintainence was done, so I upgraded anyway.)

Dat's all folk! [8)]

Hope it turns out OK for you Bob. Chrysler is pretty particular about what goes into the tranny and pacifically states that ATF+4 (soon to be ATF+5) is the only thing they want to see go into the automatic transmission.

Other than that...I just had a full tranny flush at the Chrysler dealer for $150.

This is just my opinion....With all of the past trouble thses trannys have had with the wrong fluid and constant modifications to the type fluid used...I would stick to the factory ATF+4 or ATF+5 from chrysler and not use any other kind......

[BumperBob]

Well, guess I'll be a guinea pig for Amsoil ATF then. Their website gives a lot of info, says it's compatible with Chrysler ATF+ thru ATF+4. http://www.amsoil.com/storefront/atf.aspx Charts look impressive, we'll see.

I'm happy with the motor oil.

When I changed my tranny fluid I had pretty hard downshifts and the Dealer said he had to relearn the tranny. Whatever he did it works perfectly now. As smooth as silk!

Well, just to update ya'll, the tranny is downshifting smoothly now. Just needed to give it a little time to adjust I guess. So far, so good. No problemo.

So what is your opinion on using anything but chrysler atf fluid????? And how often should you change it? Flush or just drop the pan and change filter? Thanks

[SteelBlueGT]

Thanks N/A never knew about clutches just thought my mechanic screwed up. As far as flush VS drain. It is a matter of money and overkill. The best is a flush with a new filter, followed by a flush, and least effective is a drain with filter. I did the last but did it at 30,000 miles with MOPAR ATF4. For years there was no flush and our ATF did just fine with drains new filters and coolers. Yes I know the new Trannys are much more sophisticated and new clean fluid is critical. I would not use anything but MOPAR fluid best is ATF5 if you can find it and willing to pay for it. Other fluid might be as good or even better but who knows?? AMSOIL and Redline make great products that they claim are compatible if anyone wants to try.
