Need some help/Idea's
I removed a running driving complete 5.3 motor/trans out of a 2000 Silverado 2wd.
I installed it into a 99 S10.
It starts right up and idles fine.
When I drive it, it seems like it stays in 2nd gear and never shifts up or down no matter what rpm I reach. I can shift it from 2nd to 3rd with the shifter and it will shift.
I sent the computer and harness of to 150tunes.com for the standalone harness and basic tune.
I have HP tuners and logged the test drive and read the DTC codes.
(I opened the log file when I got home and the codes are no longer in the DTC window. I will get them again tomorrow and update.) - SORRY
I basically get the following codes from what I remember:
2-3 shift
3-2 shift
vcc
1-2 shift
about 2-3 others. I will check.
Acts like the trans is not even hooked up and maybe its in limp mode???
Any ideas without the actual codes?
Stock motor/trans/torque conv/harness/computer/accessories etc...
Thanks for the help
Will
