What is the shift behavior? Does it start in 2nd when you select 1st? Check your shift linkage.

Why don't you get it back to the shop that did the Build and tell them to fix it?. If they are a reputable Shop he should do it at no charge.

Sounds like the shift linkage just needs to be adjusted. When you are shifting to 1st you are actually putting it into Park and the tranny is most likely locking up the drive shaft, not the rear doing it. When you are putting it in 2nd you are probably actually going into 1st not 2nd, and so on for the other. If this is what's happening, you can't put it in "D" drive and be able able to get the RPM's down for normal Highway speed.

Just for clarity, is it a Full Manual Valve body or Reverse Manual Valve Body? That would make a slight difference as to the shift linkage & pattern.
To me, it sounds like two bands are staying engaged when you pull it into first. |
