Ok, so here's the deal, I have an 08 Impala police with a 3.9l engine and the 4t65e transmission. I got stuck at work due to the car not moving when shifted into drive. (I tried manually shifting it into 1st, 2nd and 3rd as well.) I pulled the TRANS fuse and was able to get it home in limp mode. I checked fluid levels, they were good. Fluid was a nice red and did not smell burnt.
I still however changed the fluid and filter, and made sure the shift linkage was good, still nothing.
Fuses checked out well too.
I ordered a TCM off of eBay and installed it. It seemed to fix the problem, however not for very long. After a few drives I got the codes p0700, u0037 and u0101 so i disconnected the new(ish) TCM and cleaned the contacts.
Codes went away, but alas, still no forward movement. I'm wondering if I should try another TCM as there might've been a short and/or contact issue with the replacement..? I'm also wondering if it may be a broken band or maybe one of the solenoids went out.. But before I crack the Tranny open I thought I might ask you guys.
Thanks in advance!!
