hi, I have an annoying problem with my k2500 suburban 6,5 diesel 1994 with the 4l80E, it throws DTC 68 trans component slipping when im driving, but it stays in OD and shifts good, i dont feel any slipping at all, will go in to limp mode sometimes.
this stuff has been checked/been replaced lately
Checked the transmission fluid looks good, nothing burnt
New VSS and OSS installed
New wiring harness inside the transmission has been installed
Where do i start looking ?
