I have a -97 chrysler grand voyager(135tkm) with a odd gearbox condition. It is 3,3litre engine and 4 geared box. When the engine is cold and the gear is put into D nothing happens. After a while it goes into grip and the car starts to move. When the car needs to slow down, the first time(gearbox still cold), and the gear goes to neutral the same repeats when I try to get it to draw again. When the engine is warm the failure does not appear. Can the failure be in the torque converter? Do somebody have experience?
