Transmission

Mar 14, 2009

-   yes this sounds like the issue i am having . i am looking at the tcc apply solenoid. too. it could have some sludge stopping it from moving properly . i can go for miles with out issue and then it acts like the stall speed is several hundred rpm higher . or is in a lower gear. i know theres a solenoid issue because i have it drop from od to 3rd and it wont go back to od . if i turn the truck off and restart it, it acts fine . there are lots of little holes to be foulded by sludge.i would power the solenoids and clean them out with brake cleaner while they are open and cyclel them several times while sparying the cleaner thru them ....unless you soaked every thing and blew out every passage and ensured the were spotless this would happen ... i was waiting for a secon opinion but have yet to get one . i never dismantled the trans and it the same as yours. also if you did not flush the cooler lines and all the sludge out of it it will stay there untill it causes a problem .like the one we are having
you said the fliud was dirty ,so its possible theres still **** in the system
