Tranny Fluid's

[89GPSE]

What tranny fluid do most of you guys use? I wanted to use the B&M Trick Shift but the guy at Advance Auto Parts told me don't. He said it is type F and will destroy my tranny. So I have been looking at Mobile1 and Hurst Hot Shift. I don't like the idea of cheap fluid, and also want good shifts. Please give me an idea on what you guy use and what improvment you may have seen.

 

Thanks,

Justin

I believe using Type F will just result in firmer shifts. It won't necessarily destroy your transmission.

I thought Type F was only for Fords?? I always used ATF in my chevy trannies

i thought ATF was for chryslers, I always used Dexron III in my GM's

[digitaloutsider]

Use Dextron-III. That's what your transmission was designed to use (Well, Dextron-II, but III supercedes II), and that's what you should put in it. If you want firmer shifts, do it the right way and buy a shift kit. Don't ghetto-rig your car. You'll only regret it later.

They are actually coming out with Dexron IV pretty soon. I'm waiting until then to do my pan drop/filter change.

good idea, i'd think the price of an AVM is cheaper than a rebuild from using the wrong stuff.

ATF Stands for Automatic Transmission Fluid. Dexron I, II, III, and, Mercon and, type F are all types of ATF. As opposed to Gear Oil for a stick shift. Has anyone on here actually used any performance ATF?

[White93z34]

i haven't personally, i've just used regular old DEXIII/Merc its been working for 12 years, why rock the boat.

[THe_DeTAiL3R]

I don't think you would really notice any difference unless you got a shift kit. Stick With Dex III+

Okay...

 

Dexron II is what your car was designed to work with. If you want mildly firmer shift without sacrificing any wear on your tranny, goto ATF+3. ATF+3 is designed for chrysler trannys. It has a higher coefficient of friction and will allow for more solid engagement of the clutch packs. If you want firmer then that you can goto Type F. Type F will damage your tranny eventually. It will chew up your clutch discs because Type F actually has friction material in it. Its basically using two types of clutches at once, fluid clutch and a fiber clutch. This will eventually ruin the tranny.

 

A shift kit (transco) and ATF+3 in my friend beretta makes the thing chirp 2nd and 3rd and no problems wear wise. Fluid is clear, and very minimal deposits on the pan magnet. That is what I would do If I was in your position.

I've been using Wal-mart cheap-ass Dexron III in my Cutlass forever. Almost 200,000 miles with no tranny work.

After 2 tranny fluid/filter chages (in my ownership of the car) , mine took a dump at 150K. $2000 later she runs pretty good :yikes:

My tranny is using Trick Shift. I'm very happy, it firmed up the shifts a bit. However its a beat to hell 3 speed with almost no reverse left, a gear hunt problem and a occasionally wierd 1-2 shift. I plan on upgrading to a 4T60 sometime. I'm curious to hear more about this Dexron IV. Will it be safe to use in our trannies since it's a synthetic fluid?

What if I change my tranny fluid once a year about every 9,000 Mi. Will it still do damage. I have 70,172 Mi. as of today. And has anyone used Hurst Hot Shift?

[mihela816]

Never heard of it. Is it new?

[JoroCorona]

Regardless, over time Type F will hurt your tranny. I dont know what type Trick Shift is, but if it doesn't meet Dexron specs, I wouldn't use it. ATF+3 out does dexron in every way, thus why it gives better shifts. I run ATF+3 in my lumina. Before I started having engine issues, I was neutral dropping it every other day, and lockout shifting it when I wasn't neutral dropping it. I am very abusive to the tranny and it shifts like new. ATF+3 is what I would suggest to you.

I don't know how "new" it is. The bottle looks old. But i see it at the auto parts stores around here all the time.
