1997 Other GMC Models V8 Four Wheel Drive Automatic 160, 00 miles
My Suburban has run great until I started commuting. I've had a trouble keeping Antifreeze in the overflow 9so I'm sure the engine is getting extra warm but not overheating) When the engine gets warm after driving on the highway and I get off the highway, the first time I accelerate it gives a rough shift from 1st to second. (This continues on in the city) I've been checking the transmission fluid regularly and it is getting low. We had someone SUPPOSEDLY change the cooling lines and check it but he obviously didn't do what was needed. I really don't want to damage the vehicle by not doing what it needs. Any suggestions?
