just went for a drive in it.. doesn't do it when its cold..
tranny fluid was changed in mid may ( pan drop / filter change, no flush )
It feels like you're going thru the rumble/wake up strip but less harsh..
It almost feels like in O/D the torque converter is slippin too much. ( I know it'* suppose to slip some )
So a few questions more folks
a.) Where is the TCC Solenoid located on the tranny? ( Can it be DIY? )
b.) How do I check the TCC bore?
c.) Is there a plug or something that can disconnect the O/D ( TCC lockup ) but still keep 4th gear? ( Since he may not want to fork out the $$$ to get a tranny fix / rebuild )
JR do you know if the issue also affects 4t65E HD??
My car stutters as soon as it engages O/D then its fine and free revs a lil too much before engaging O/D
