Automatic Transmission problems of the 1997 Chevrolet C1500

Traveling approximately 25 mph I began for an upcoming stop sign, two school buses were already stopped as I applied the brakes the peddle went quickly to the floor with little results, I was able to put the truck in low gear, turned onto the shoulder and with the emer. Brake and what little brake that was left I was able to get stopped safely. I would learn the welding on the upper shock bracket had failed allowing movement which allowed metal to rub against the brake line which runs past that area. The line failed with the lose of fluid and the brakes. Repairs included replacing of the upper frt. Susp control arm assy misc brackets and shelds and rewelding upper shock bracket. It also included replacement of the brake line.

1997 Chevrolet c-1500 p/u auto trans has hard shift from 1st to 2nd gear. I have researched this and found a large number of g/m owners have experinced this defect and g/m has not or will not recall or repair this problem.

Transmission went out without prior notice. He was traveling on highway when vehicle started jerking, and vehicle had to towed. Dealership was aware of problem.

Dealership very helpful with this and several other problems. Seems to be a major problem with this transmission. . Read more...

No summary.

When driving at 60 mph to 65 mph, tranmission slips and there is a loud knocking noise coming from the vehicle. Dealer can't determine the problem.
