hi all
no i just want lock it.I am certain it's to close.
just to close when I want.i have a code 62 and 23 when the road goes up and when i must change speed 1-2,2-3 good ,3-2 .....limp mode. rpm sensor new,vss new,tps new,shift selector new ,pack solenoid new..but if i accelerate slowly no limp mode. I suppose that the converter sticks badly or this takes off.
thank's for yr help

Torque Convertor Lock-up mod

To find the remove the trans harness conector from the fire wall it will be the one closest to the fenderwell and find the purple with yellow tracer wire.

I don't know if this will help your problem though.

manually locking it wont stop it from slipping
