Tranny fluid
I am about ready to change my tranny pan and someone told me since I have a shift kit I should use type F tranny fluid. I have always used regular tranny fluid.
Thanks

I wouldn't. F type fluid is Ford fluid as I'm sure you know. I've heard from many sources B&M Trickshift is nothing more than Ford fluid.
From what I've read F fluid has more friction modifiers. What this means is more wear on the clutches. Not sure on this, just what I've read. All this reading was done on the internet, so you can take it with a grain of salt. Why would you need fluid that would cause less slippage with a shift kit?

Type F has its advantages but I am a firm believer of not mixing fluid types in transmissions
If you have been running dextron for a while and have no intention of pulling the torque converter to drain it. I would stick with it as your clutches and bands are soaked with it, and to get all the old out your going to need 5 gal buckets full of type F to flush all the old out.

use dextron 2 fluid in your GM or universal fluid if and when you gt a Ford and it tells you to use type F there is no need for different fluids for a shift kit

The only thing I would use other than dexron III is a synthetic that is compatible with it. The transmission was designed to run on dexron.
Ford has three automatic transmission fluid specifications: Type F (a non-friction modified formula for most 1964-81 transmissions), Mercon (a friction modified ATF similar to Dexron II for 1988-97 transmissions), and Mercon V (Ford’s latest friction-modified formula, introduced in 1997). General Motors has two specifications: Dexron II and III. Both are friction modified formulas and Dexron III can be used in the older GM transmissions that originally required Dexron II. This is why the Type F is bad, it has no friction modifiers. That's why it shifts more harshly (bangs) changing gears. Its harder on the transmission parts also. It allows it to slip very very briefly and when it catches back this is what causes it to shift harder. This all happens in one second or less. Its up to you if you want to use Type F transmission fluid. I personally wouldn't.

I heard Type F, ran cooler ?
(or didn't get as hot as Dexron II) ??? I can tell ya, I accidently put a quart in my 700r4 in my 88 blazer (mixed up trunk boxes with Mustang) and my tranny started slipping real bad real quick, took down the street less than a mile away and they did a transfusion (dont recall technical term), and it was 100% better ASAP. I'll report back after I run my rebuilt Turbo 350 one day, it's full of Type F, waiting on my engine to come back. Bill |

I always heard what mike did about the B&M being nothing but blue ford fluid. Here's what AS AN OLD TIMER that i do know , the ford fluid was preferred for firmer shifts because it is more absraive(for lack of a better term) and therefore causes the clutches to grab a little firmer. I was just looking at the B&M fluid today and for what they sell that for I can buy REALLY GOOD synthetic. I am going to go to synthetic in mine after I break it in. DAVE
