My gmc Sierra 2500 is in limp mode after replacing planetary gears in Allison 1000. Primary code is tcm(mil request). There are about 20 secondary transmission codes. Double checked all wiring harnesses. Any ideas?
Without specific instructions on what you did, we cannot help.I signed up to this forum to try to get assistance from experts so I can fix my truck myself. If I had the money I would have taken it to a shop the first time. Not looking for advice on who should fix my truck. I will get it figured out elsewhere.

Fuel in oil is definitely not a good sign.Thanks for responding. Sorry to hear about MikeL. I think he passed 1 or 2 days after I signed up hear.
I did get a cheap scanner ($100) , cleared the codes and got 2 codes now p0700 and p0872 (t fluid pressure sensor/switch c circuit low). Not sure why AutoZone scan had 20 (secondary codes). I did have fluid in the pass through connector. Dried it out with air and trying to find a new one. Not sure how much time and money the truck is worth with 212k miles, rust is taking over and fuel in the oil. At this point maybe I will get lucky and get the code fixed and the truck will last a year or 2 without removing the trans again.
it won't last that long if you don't fix the fuel in oil issueThanks for responding. Sorry to hear about MikeL. I think he passed 1 or 2 days after I signed up hear.

Both those codes are ECM codes (P0700 is a generic code given to the ECM stating an issue with the transmission).Thanks for responding. Sorry to hear about MikeL. I think he passed 1 or 2 days after I signed up hear.

The scanner is Innova 3040rs. I am in the Cleveland Ohio area. Thanks!
