or 1st gear car moves good but will not up-shift.
1,2,3,4 gear. 1st slips or works??????????????
name 4T60 (transverse 4speed box) GM./
DIY?
check fuse first
scan the PCM (the PCM has TCM) the TCM tranny brain and if TCM is not happy it tells you why
so all carsChev 1992+ must be scanned, first.
the 4t60E box is electronic shifted. scan it.
what is miles on car.? 100k,300Kwhat?
causes are vast, (ever see inside any A/T box)
the next test in the book is pump pressure test
PRNDL
Automatic drive
