904 transmission shifting adjustments
Hello to all at FABO, its been a while.
I had my 904 transmission rebuilt at the local transmission shop and im having some problems with shifting. The same problems i had before it was rebuild, i was hoping the rebuild was going to fix this. it needed rebuild reguardless because the clutch materials were heavy in the oil pan, so i assumed that was the problem. When you are on it, shifting from 1 to 2, and then 2 to 3, its a long shift engagement almost like its slipping, you have to get off the throttle and then get back on it. When you drive it nice and easy it shifts fine.
How do i get that solid shift when im shifting at wot.
This has a B and M after market cable shifter, where you simple push the shifter forward when your ready for the next shift. I looked at the adjustment when i had the oil pan off, and its sitting in the right detents.
It doesnt have a kick down lever any more, if i remember right, the guy i bought it from, zip tied that lever in the applied position...does that make any since? now that im thinking about it, i need to check what position it is in currently.
I wish i would have done my own rebuild on this one. Im not sure how it was built and rebuilt. Valve body options like manual reverse valve body.. whats the point of forward or reverse shift patterns?
Also I put a 3" dual exhaust kit on from summit, i have hooker headers, and the thing is still really load. I used summits turbo mufflers #633230, is there another performance muffler out there that will hold up to the horsepower, i need to dyno this thing but i think im putting out around 300-400 horsepower.
Also was thinking about changing to hood scoop, any ideas?
Thanks
