What other A/transmission fluid do you use?

FWIW I did a total fluid replacement following Timmy's tutorial on Youtube a couple months ago, and installed my B&M 70268 cooler at the same time.

I went to my local dealership to get my ATF and they gave me 14 quarts of Mobil1 synthetic that said it was made for Ford and Chevy trucks or something on the front. The guy at the parts counter said that's what their distributor has been giving them and that it's fine, I think it was Dexron III.

So far no issues.

Well this has been informative for me, last August I did a full exchange on my '99 using the T-IV because it said on the bottle that it was a direct replacement for the T-III. So now I have to pump out $100 worth of the wrong fluid and use after market fluid ??

FWIW, I haven't had any issues with the trans since I did the exchange. If anything, it definitely shifts better.

That's up to you. You are correct as it does state that on the bottle. If you not experiencing any problems with the fluid that's great. Just keep it in mind the next exchange or time to change it. It probably be better to use another fluid. As there are documented cases that our transmission can slip and not function properly with TIV fluid.

Mostly the TB come out after issues start happening.


Thankfully, we have many of other fluids that are Dexron III and II compatible to choose from.

You're fine. Been using this spec for a while. I trust it more than an unlicensed Dexron. Plus all the major synthetic fluids allow cross compatibility between Dexron 3 and T-IV, even the beloved Maxlife ATF. Haven't ever heard of a failure by using T-IV.

Speaking of Maxlife, it has specs similar to Toyota WS in order to meet WS spec. Why not just try straight WS in these transmissions? I've already heard success stories of Dexron 6 in these, which is another low viscosity ATF similar to WS.

As long as you don’t have torque converter shudder and it shifts fine your probably ok.
Who’s to say if it would have a negative impact on the torque converter and clutch packs.

Just did a drain and fill with a new filter and put in Valvoline Full Synthetic Import Multi-Vehicle and after reading this thread I am starting to think its the wrong fluid. I had some hard shifts and slipping previously which I thought were due to low fluid levels but it has seemingly gotten worse and now I have a whirring noise at cold start. Is this due to the fluid or is something else going on here?

These transmissions aren't picky with fluid, you may only notice slightly different shift quality depending on what's in there. Matter of fact the fluid you used is probably better than Maxlife since they didn't thin it out in the quest to meet WS specification. If you already had hard shifts and slipping, the damage is probably already done. I would keep trying some drain and fills with Castrol High Mileage ATF, it is slightly thicker and contains some additives to make up for wear. Worst comes to worst, throw in some Lucas and start saving for a transmission.
