When my car is put in reverse my car jerks and when it goes to d4 it's even worse
my cousin says it's the motor mounts ... I want to no what you guys think...it's a 98teg ls
your torque converter is probably gone but first check out the shift solenoids. back when i had my auto ls that started happening to me so i just sold it to save the headache but the guy who bought it put in a used tranny for around $200
