Guys, I need help. I run a Mopar powerplant in my mod, and I want to use a 904 tranny. I know that I'm probably barking up the wrong tree, but I also asked this question on the moparchat site as well. The question I have is this: Can a 904 be modified in the same manner as a 'glide? What I'm referring to is the drilling of the low/reverse piston to bleed off line pressure. If anybody has any info on this or any opinion I would really appreciate any response. Jammin, what do you think?

Thanks guys, I'll figure this one out. I think it will work, but haven't gotten any "warm fuzzies" from anyone else. May just be a trial and error thing. Anyway, thanks for the help and ..................See ya at the track!!

I have never messed with them but I think Burt Brown can help you. While he probably won't spill any secrets he may give you some free advice.

The Torqueflites can be made into Direct Drives just the same as the Powerglides using the same front pump plumbing with the hose and ball valve set up. I would recommend using the TF 904 instead of the 727 because the 904 weighs about 115 lbs and the internal parts are smaller in diameter so they would use less horse power and spin up faster. I have a friend by the name of Rick Page who won the points championship at Lorain Speedway with a 360 E-Mod with one of my Direct Drive 904s. The important thing in doing when using this type of trans in the Direct Drive setup is using the special blue racing clutches in the clutch packs. They will take the slip of taking off from a dead stop and last longer. This and a TF-3 Transgo Shift Kit will give you a transmission that work well and win races. If you do not run a cooler, make sure yo run the front cooling line to the rear fitting with a true 5/16" tubing, this is what lubricates the back bearings, bushings, and thrust washers. I also recommrnd a aluminum deep sump pan, this helps to prevent left turn starvation of the fluid sump from G-force. Good Luck my Dirt Forum Friends! Burt www.burtbrownracingtrans.com
