Crosley Sounds like the T-400 forward clutch is a problem.

Was the T-400 parts replacement job performed with a full paper and rubber kit? Sealing rings in this T-400 were metal or a teflon looking material?

Clearances on the clutch pack of this T-400 were set at what clearance?

What condition was the pump in this T-400 ? Was the side clearances of the gears checked in this T-400?

72GMC496Stroker So to add to this, I was able to take the truck down the road, still slipping in 1st however I found out that it hits 2nd hard and sticks and the same with 3rd. So at this point the transmission slips in 1st on take off very badly however about 20mph it will hit 2nd and doesn't slip...

Anyone have any thoughts on where to look, is this a valve body issue, a clutch issue, ??

T-400 slips in drive but has reverse after rebuild

Good Morning,

Last week I rebuild my 400TH, it had been slipping in 2nd and 3rd before the rebuild. I found plenty of burnt clutches that I replaced along with a few bushings and seals. Hard parts were alright with little signs of wear. I put the transmission back in yesterday put 6 quarts in it and started it up. Went into reverse (on jacks) and it took off after a few seconds, then in drive it didn't go. I checked fluid and added more for a total of 10 quarts. After that the the trans rotated in both ways.

I dropped the truck and backed it out of the garage, however when I drop it into 1st you can feel it engage but it slips with the slightest hit of gas. I drove it backwards around the yard trying to get fluid moving however I could get more than a roll foward in 1st gear and when it went into 2nd it acted as if it was in neutral.

Any thouhgts on where to start with this? Reverse is solid and I am confused at this point. this was my first go at a rebuild but really didn't see any reason why it wouldn't work.
