    Limp mode after new planetary gears

    Truck is good now! No codes. Rides good. Hopefully it is a permanent fix. I appreciate all the helpful advice given here. I read the valve could have been stuck because truck was shifted into gear with only 8 qts of fluid instead of 13. My mistake for trusting the fluid capacity advice of...

    Limp mode after new planetary gears

    I think so. Should it drop in all the way by itself without any spring pressure?

    Limp mode after new planetary gears

    I opened the valve body. Everything looked clean including the filter screen from what I can see. Should I use the boring tool or scotch Brite or another way to fix that stuck valve. I was also going to replace the pcm. Back in 2003 MikeL said he never saw a bad pcm. Someone else said they...

    Limp mode after new planetary gears

    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)...

    Limp mode after new planetary gears

    I had auto zone do the scan because I don't own a scan tool. I can go back to auto zone or buy a scan tool. Will a cheap scan tool work for this?

    Limp mode after new planetary gears

    Took the the trans out of the truck (04 gmc sierra 2500hd 4x4 Duramax with 212k miles) because it was grinding in 1st gear and didn't have 6k to pay the experts. I replaced the whole planetary gear set because a thrust washer was destroyed and one of the planetary gears looked bad. (I think it...

    Limp mode after new planetary gears

    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.

    Limp mode after new planetary gears

    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?

    Planetary gear set

    I have 04 dmax sierra 2500 Allison 1000pk that needs new planetary gear set. I have seen 7 different used sets for sale for Allison 1000. I found 2 sets that both have a p3 sun gear with 49t which is what I have. My p3 ring gear count matches the 1 set and doesn't match the p3 planet gear...
