It's time to change that transmission fluid again, I just wanted some opinions on this stuff before I put it in. Thanks.

I've used the B&M, the Hurst Hot Shift, and the Red Line stuff. I would say they are all about the same. However, they did actually firm up the shifts a touch more and it seems they can withstand a bit more temp. The Red Line stuff is supposed to be a little better, but it's also a little more expensive. I would look into the Royal Purple stuff. I am not sure if they make trans oil, but everyone is raving about their other stuff so I imagine it would be just as good.

 

The b&m trickshift is good,i use a few quarts in my car when i do fluid/filter changes,it gives really firm shifts and seems smoother,but i just still couldn't get over the weird blue color of it,my dad was like "what the fu&* is that?".

Here is what you should use. Dexron III or Synthetic. No 'trick' oils. If the tranny doesn't shift hard enough that is a calibration issue.

 

All trick shift is made from is Type F fluid with friction modifiers and funky blue dye.

The problem with type F is it oxidizes more rapidly than the Dexron and will require you to change the fluid much more often.

Get a synthetic Dexron, you can't go wrong. If you want firmer shifts get a corvette servo and/or put firmer springs in the accumulators.

 

I agree w/ Joel. I put my B&M shift kit in and used dexlll,drained it and put type F in and it shifted much harder,I have ran type F in all my vehicles and never had a problem.Just makes for better shifts.

 

For all the years before shift kits were widely available (and before B&M introduced Trick Shift!), we all used Type F... "shift kit in a can"... most of the trans builders in those days specified Type F for their product in fact.

The B&M product is nothing more or less than Type F fluid produced at a refinery local to them, with blue dye added to make it look different. It's nothing special. Nothing wrong with it, but nothing special either.

Early F*rd transmissions had less than half the total clutch area of GM ones. So a special fluid had to be invented for the Brand F POSs. It is a slightly thicker base with about twice as much "friction modifier" additive, to help the clutches grip better. That's why it makes better shifts.

I would recommend a good quality Type F and save the difference between that and B&M for something that makes an improvement.

Like a Mobil-1 oil change with an HP4 filter...

 

If you have never had the joy of working on a heavily varnished Ford Transmission you cannot fully appreciate Type F oil. Actually it is the LACK of friction modifiers that makes for the firmer shift. It also lacks the ability to handle heat and breaks down into sticky, smelly varnish like fluid (sometimes gobs rather than fluid).

Ford stopped using this oil in 1977. It is no more common now to see this problem on Fords than any other vehicle since they changed to Dexron (and equivalent) oil. BUt hey, it is less expensive to buy Type F than to properly modify your transmission. Your choice!

 

If you want the effect of firmer shifts due to the lack of friction modifiers, but don't want to settle for petroleum base fluids (like B&M or Type F) with their problems mentioned above, go with AMSOIL's Super Shift. Fully synthetic base, no friction modifiers, firm enough shifts that they don't "recommend" it for street driven vehicles, protection from wear for the gears, pump and other metal pieces from the synthetic base.

I refilled my TH400 with it, so still had some of the "steet" syn ATF in it. The shifts are VERY precise, to say the least. It isn't particularly harsh on the road because of the vacuum modulator and the presence of about 25% ATF with friction modifiers.
