My 02 i just got had a codes for the solenoid pack fault. So I have had that replaced along with new filter and fresh fluid. The tech also re-calibrated it. It drove great for a few days then started shifting rough occasional for a few days. Then one day it went rough shifts till it went to limp mode with CEL. I don't have the code but I think he said there was a pressure sensor that threw the CEL..... He cleared it and it acted fine for a few more days. now some days its pretty good but occasional still goes in to limp mode. I have noticed a few things like it is always better when cold vs warmed and shifting issues range from not shifting when it should running higher rpm's or still having rough shifts/shuddering. Any insight would be appreciated. No current CEL transmission codes.
