hey guys lately i have been having some problems with my torque converter locking up. I have a yank 3200 and lately it has been throwing a code and has not been locking up in overdrive. The other day i was driving on the interstate the the check engine light came on and it wouldn't lock up after that. Then when i got home it wouldn't go into first either. I reset the computer and it worked. But still sometimes it seems like it doesn't want to lock up. Whats the deal?

p.s. i have removed all of the torque management.

 

Engine missfire codes can interfear with converter lockup.It could be as simple to fix as a sparkplug or wire change.

 

I have this problem with my SS3800. I guess its somewhat normal for a stall higher than 3000. Mine would throw P0757, and keep it in 2nd and 3rd gears. I just turned off the code in edit and its all good.
