Trans issue. please help!
99 venture 4t65e. Initially I blew a PCM fuse. After I replaced fuse, van went into limp mode with a TCC PWM DTC. Found a blown TCC fuse, replaced it. Van is now out of limp mode, but will not shift past 1st gear. No DTC's present. I can't seen to find any issue, and have traced all wires.

Hi !
A common problem with the 4T65E auto transaxle is the pressure control solenoid (PCS) causing the hard shifting and in most cases upshifts only. If this is the case with yours then a scan with a trans capable scan tool may reveal a stored DTC of P1811 (max adapt, long shift) which would confirm the PCS is suspect.
You have shown the error codes?
