Someone was saying today that they put ford trans fluid in their th350 trans. When I asked why he said it makes it shift quicker as a shift kit or something. I have to admit I heard quite a few tricks but not this one. So can anyone tell me the pros and cons of doing this. Or are we better off buying the B&M TRICK SHIFT?? <img src="confused.gif" border="0">

So I take it that this is unheard of and the guy must be stupid for doing it. HUH <img src="graemlins/nono.gif" border="0" alt="[nono]" />

ive run type F ffluid in my th400 for 20 years or longer no problems, type F has a friction additive lets clctcher and bands apply quicker

When you buy a B&M shift (improver) kit at the auto parts store, It says to run F type fluid in the trans after the kit is installed.

Type F fluid in a GM tranny? Not a good idea... I'm a Lube Tech and I've seen some tranny's blown up due to incorrect fluid use. I'd try something else in yout tranny unless you want to be purchasing a new one in the near future <img src="graemlins/nono.gif" border="0" alt="[nono]" />

NEVER use Dexron in a Ford. That will do damage. Type F can be used is any tranny and does improve shifts in GM and Chrysler trannys. B&M TrickShift is basically Type F with their secret elixers (blue dye) added. Type F in a GM is a very old hot rod hop up trick and should actually help tranny life due to the firmenr shifts.

I was told to use half dexron, and half typeF by the guy who built the tranny for my S-10, was told it would make the tranny shift quicker, don't know if it actually made a difference, but I do it anyways.

Using Dexron in Ford trannys is fine. If you add Dexron to a tranny and it starts slipping or other troubles there was an underlying problem to begin with.

The line that Dexron causes slippage, or other problems is not true . In most hotrod applications Dexron or Type F is fine. Type F has less friction modifiers than Dexron/Mercon and Type F was created to correct shift noises in the early trannys. The modern aftermarket frictions will function with either fluid.

Where a problem is in late model Fords that require Mercon V fluid. Only use Mercon V when it is spec'd .

In late Mopar products using Mopar products produce more consistant shifts in the FWD stuff.

Imports........ use the recommended fluids. There are additives out that work well in Dexron to allow useage in some Imports and Mopars.

I just rebuilt a C-4 tranny for a guy. He had the tranny serviced and a day later it started acting up. He was sure the service company had added Dexron fluid. When the inner lip seals came out in pieces since they were so hard the problem was obvious.

If you have a tranny that has started slipping in the cold mornings....... add a quart of engine oil to it. 10-30, 20-50 I don't care. This will cover up the hard seals for a while till you over haul the unit.

IF you like sythetc tranny oil.... Amsoil is good and Mobil too.

Type F into a Powerglide or TH tranny was a cover-up measure I saw used in second hand car lots 25-30 years ago. Now that I have a better understanding of how they work it makes sense. Some of the other things I saw done as a matter of routine back then would get the shop owner a fat lawsuit these days.

Hey, just tryin' to make a livin!

I walked into a Tranny shop to buy a stall converter, asked for B&M Trick shift, the guy told me hey, use type F and it will be fine with same results as B&M. I do recomend that if you have money to burn, accept no substitutes.
