Transmission Problems? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Hello. i need help. let me know what i can check on this 6l80e 3rd gear problem
Have you done an air test on the clutch to see if it has bushing wear not allowing full pressure to get to and maintain to the clutch. Burning clutches means its not getting enough fluid and pressure to it to keep it tight. If the piston seals were not torn then its leaking prior that. Next is to see if anything in the valve body is blocking fluid flow for 3rd gear.
Thanks for using Just Answer, and rating me so I am compensated, Chris
I installed new bushing in the drum that had the bad clutches . air checks were done everything worked . im just wondering if it has a bad pressure solenoid. . of course its a 700 $ computer in the trans. . i was driving the car home tonight. it has a very harsh shift into third at normal throttle .
Did you go through the upper and lower valve bodies to check for valve issues?
Did you replace the TCM/solenoid body assembly?
No. i never went thru valvebody. just cleaned it. i never bought the tcm/solenoid assembly . 700 bucks.
Since you have confirmed the pressure loss is not at the clutch area then its time to go through the valve body to check there for scoring, broken valves. If okay then TCM replacement is needed.
Ok. i will pull the valvebody and check it. a new tcm is 700. that will hurt...lol
Yes they are expensive.
Since i have never took apart one of those valvebodys . it will take me some research . i have direct hit. it shows some disassembly procedure
If you find your info is not helping let me know and I will try to upload some info on the valve body.
Send me as much info you can. i need it. thanks.
Thanks. i will keep you updated
Hello again Chris here,
I went through the valve body today it looks excellent so I ordered one of those TCM for the transmission
Thanks for the update, anything else needed from me?
I am installing the tcm today. ill give you any update after a test drive.
