That's what I was afraid of. I did little kick on 1st and full hookup in reverse. I have the spare parts and all that jazz just hoping I can get off without needing the change because I'm alone on this projectYour only hope is that the shift linkage is messed up. If that's not it, you're almost surely needing the trans torn down. IIRC, there is a sprag that fails, so it will go in manual low, but not drive. Have you tried all positions of the gear selector?
I'm hoping for the best the issue other than the fact that I'm alone is I'm stuck doing this In the dirt, I dont even have a drivewayIf you are going to tackle this alone.
First please be careful. I highly recommend the big harbor freight trans jack. It can hold the trans and a np205/np203 mated.

Big maybeI had hoped that wasn't the case, dirt. Piece of ply might be the thing. The jack only needs to roll front to back maybe 4 to 6", to remove and install the trans.
Will there be any around?
Is there a gasket between my transmission and my t-case? Because if I'm changing transmissions I'm gonna have to remove the t-case from the old oneI did it myself. Just go slow, and get plywood for the jack to roll on.
You can leave the cross connected as well.
Th400 3 speedmay be an oring. Is this a 700r4 and np208 combo or th350 Np208 or ?
I didnt get to destroy it lol, I'm owner number 7, number 8 if you count the prison it used to work at. Idk how they totalled it that's why I'm hoping maybe it's something stupidyou destroyed a th400, my god man what where you doing ? yes there is a gasket
