Hey guys i was wondering if yall could guess what the the problem is with my tranny on my 97 z24. When doing a lot of stop and go driving after a long period of time like over and hour it shifts roughly . Its an auto by the way. It shifts hard and makes a loud bang when it does. After letting the car set for a while it stops. Its only done this 2 times within the last month. It seems like it only does it after the car has been drove slow with a lot of stop and go driving. It doesnt feel like the trans slips or anything and after the car sets it shifts perfectly normal. Im thinkin its a sensor causing this. Talked to one guy and he said it could possible be a trans fluid temp switch. Ive never heard of it though. Any info would be appreciated. Thanks
