1994 saturn SL1, 1.9 SOHC automatic upshifts very hard, have cleaned trans speed sensor and connector, replaced trans mount, TPS, and filter. Am replacing speed sensor tomorrow. Is this a common problem? The coolant temp light flashes tranny codes on this car, shows code 95. 130000 miles. Could this be a valve body problem? I have some new info.I drove the car some today and the check engine light came on and the trans began shifting smoothly.I drove 20 miles like this and the car drove fine at all speeds.I cut it off and restarted and the light went out and it started banging upshifts again. Ecu shows code 11, tcu shows code 13, 84, 95. Thanks for any help!I have no credit cards and no idea how to donate on line. How about some free help?
have the same problem?
