I have been through my tranny at least 4 times breaking and upgrading stuff and this last time it was running great for 20,000 miles until I did a burnout and smoked my 2c and 4c clutches.
So I replaced them and upgraded the 4c housing to a billet one and replaced the solenoid pack.
Now it shifts perfect from 1st-5th but the 5-6th shift is shuddering 4 times then locks in hard every time. 5 is od clutches and the 2c clutches and 6th is od clutches and 4c clutches.
So something is going on from the 5 to 6 shift.
New revmax valvebody and pump and 550 rebuild kit.
I pulled the tranny and air tested the clutches and there still perfect and there is not much clutch material in the pan magnet.
Could I have broke something in the valvebody or pump, or is the new shift solenoid bad.
My snap on scanner showed the 5 and 6th gear shifts and line pressure perfect and no codes.
I'm beyond frustrated with this tranny.
Thanks for the help.
