1997 Chevrolet 350 Doesn't Shift right while in 4X4HI
i have a really odd question i have a 1997 chevrolet K1500 4X4 with the 5.7 350 and the
4L60-E tranny the truck runs and drives fine in 2wd. however when i use 4X4 HI the
transmission doesn't shift properly its almost as if it shifts to early causing bog and at
WOT it will not kick down a gear or 2 it remains in that same gear and struggles. if i
manually shift the gears all is fine.. although this is not good for the transmission and id
much rather just fix the problem. i should also add sometimes it runs fine then all the
sudden bam.. starts running like a bag... take it out of 4X4HI runs normal put it back in
runs good for a while then starts messing up again.
