Hi Mr Scotty I am engineer Qasim Muhammad from Iraq I have Chery A5 car I have problem with the transmission when the car heat up after 15 min approximately the problems in the transmission began so the transmission not shifting its remains on gear 1 and the speed remains below 20 km/h and speed gauge tilting between 100 km/h and 20 km/h could you help me please
This is the problem

odds are transmission is going out, chevy makes crappy trannys. Have a pro with a dealer level scan tool road test it and check that FIRST
