I was at NMCA a couple of weeks ago and after ATI fixed my 8" to brake stall higher than 2800 it was working great. 3 practice runs cutting lights, won 1st Rd .005 light, I thought I heard a pop backing up to my pitts, 2nd Rd bang in third coming out of the burn out box and fluid under it. Looking behind the block cracked bell housing. I will pull it shortly. I bought a 78 HD out of a Motorhome and it has straight cut gears and 6 clutches in the direct drum. I am putting together a spare trans with manual reverse pattern valve body. Is there a way to see what ratio is in this low gear set or are all of them stock?
Those would be the standard straight cut gears. A 2.75 low gear is aftermarket only, and the easiest way to ID it is the sun gear has two different diameter gears. And yes, with a 400, start in 2nd and nail it hard enough to break the tires loose immediately in the waterbox, and then shift quickly into third, bring your rpm up and then disengage the line lock... as it starts to walk out of the box, lift completely off the gas. You should hear the slicks chirp just a touch as they bite the starting line. Getting crazy with giving it more throttle as it comes out of the box, breaks parts and destroys torque converters. JW
I am not a TH 400 application expert, so I could not say for sure, but I am not aware of any factory 2.75 gear sets. JW
What do you guys think about the TCI 221100 Manual reverse valve body? It don't look like it comes with gaskets.
Yup, but you usually get what you pay for. Maybe 800 will last much longer, I don't know. Some of the experienced racers should be able to speak to that.:TU:
I used the TCI one for years. A serious bracket car will have no problem handling a trans brake. It should already have the upgraded driveline stuff. JW
Yea, Mosier 12 bolt, solid lower and adjustable upper arms and a driveshaft to hold 1800 HP since I twisted the other one! I night want to get a GForce trans cross member though. I'm wandering if that's how the case broke.
