Transmission rebuild
 

Recently bought a blazer off Ebay. Engine runs great but transmission shifts from 1st to 2nd fine but no 3rd or 4th. Got code p0753 so replace shift solenoids A and B replaced filter flushed transmission. Code p0753 is now gone but still no 3rd or 4th. When transmission is at operating temp read full when is cold reads way over full. What in the world?

Pump and input drum seem locked together and came out as one. Did I miss some thing or are they just stuck? This is from a 2001 s10 Blaze?

Did you pull the "O" ring? Around 2:23

Transmission rebuild
 

Transmission came from 2001 blazer 4x4 bought cheap because of transmission. Rebuilding it but both input shaft and separator plate seem to be 1993 to 1999.Separtor plate has a spot where a ball bearing goes that is built up. Tag reads 1TAD and torque converter has tag that reads DCNF 2420. Seems to have been rebuilt before and one trust bearing and the 3 4 clutch release springs were missing. Any insight would be greatly appreciated

Question is, is it possible that a transmission built in 2001 would have what appears to be a 1993 to 1999 input shaft and separator plate

Thanks for the help in rebuilding transmission. As it turns out all works as if it were new. Again thank you
