2001 Chevy Malibu w118000 miles automatic started shifting hard into drive and 1st gear after that runs smooth Check engine light is on at the same time the problem started any help?

Answer 1

2001 Chevydisconnect your positive and negative cables on your battery for about 4 minutes and see if that reset the computer , if not then go to auto zone let them hook up there free diagnostic puter to read the check engine light ANSWERyou may want to have a transmission tech. check the pressure control valve soleniod. which electronically controls the transaxle

it seems that most of these complaints come with a water temp sensor problem. my 01 Malibu had a plugged thermostat, car was warming up but not spitting any heat inside the car (MIL was on too and still is, I'm going to try disconnecting the battery) and the transmission started shifting hard when the MIL came on. changed the thermostat and the MIL is still on and it's shifting hard still... in the summer time in traffic or just really hot days (95 F +) the car would shift hard sometimes but after i got cruising, it worked fine.
