1995 Volvo 850 Transmission

Post by mwilk316 » Fri Apr 05, 2019 7:55 am

I have a 1995 Volvo 850 that I recently replaced the PNP switch due to the known symptoms that would indicate this. I pulled the codes from the A1 socket and there was a 313 code which I cleared. After the replacement of this switch, I verified that every thing was indicating properly- park position, reverse position, neutral, in the 3 position the orange arrow lights up solid, in the L position the arrow lights up solid, winter mode the arrow lights up solid- the econ/sport switch indicates correctly.
The issue I am having- when in the drive position the car stays in 1st gear and will not up shift. In the 3 position the car shifts normally through the 3 gears and in the L position the car shifts through the 2 gears. I am baffled as to what could cause this anomaly. I am leaning toward a TCM problem- I am going to run through the diagnostics/ testing of components this weekend but was hoping to get some ideas from the folks here on this forum.
Thanks for your input.

That's a puzzler. Did it shift just fine before the PNP work?

No it did not- When in drive it was stuck in what seemed like 3rd gear (I believe this was some sort of limp mode) and the orange arrow was flashing. Performing the "key on and moving the shift lever from low to park around 20 times" cleared it for awhile but it would eventually come back.
