so i jsut put in a trans go jr on my 07 LBZ and i checked over everything b4 i bolted up the tranny pan. then got all the fluid in and everything checked and started it up and let it warm up and then the P0700 and P0877 and it would go through Park reverse neutral drive and manual and first but you wouldnt move anywhere. then it i dont know weather the tranny started getting warmed up sum fluid flowing but then it would go in reverse and nothing else and then after a while in drive, so i lightly drove a little bit and it wouldnt go past 3rd gear, then i stopped and dropped it into the manual shifter and it was still in 3rd gear. so i dont know wats wrong with it, SOME ONE.... anybody help
