I brought my car into a couple of trans shops today and at a couple of the places I got the same results.I was told that its a trans lock-up solenoid were sometimes it goes into overdrive & sometimes it don't?? Also I have a 9" Vigilante torque converter (lock-up) so I thought it could be the converter but I was told it was NOT has anybody ever experienced these problems?

PLEASE HELP!

 

i had on e go bad in the 700r4 in my van.it would shift to overdrinv but wold not lock the converter.the plus side is it is easy and cheap to change!

 

I just really hope this is whats wrong with it in my 4L60E sometimes it will lock up & sometimes it won't, but it shifts through all of the gears completely fine?

Thanks

 

i hope for your sake it is the selenoid.if not it is the converter.

 

I'm really not too worried even if its the converter at least its NOT the trans.
