My daughter's 97 Mitsubishi Galant ES has a problem that results in a clunking sound only when climbing a steep hill. It seems to occur when the auto transmission drops down to a lower gear. A clunk or thud is heard. Otherwiuse the car runs great.
Trying to figure out if it's a transmission problem, torque converter, rear end, or universal joint problem.
The problem doesn't seem to happen if one climbs the hill slowly. That is, if she stays in low gear all the way up. But if she drives normally and the transmission downshifts, that is when the problem is apparent. It's like it is dropping into the lower gear hard.
Anyone have any ideas?
Thanks
