Having problems with your 1993 Buick LeSabre ?
Buick shakes, guns then almost stops
\015 1993 Buick LaSabre. Out on road at 70mph, tried to put on cruise control, didn't work at first, then it did. Then car started to shake like road very bumpy then lost power then power came back. Check engine light came on. Dial about transmission usually never goes over 3, shot up past 4, then down again.\015
This sounds very much like a torque converter/transmission issue. i will assume the transmission dial you're speaking of is the tachometer? which measures engine revolutions per minute. to confirm, one could possibly unplug 4-wire connector on transmission near radiator and test drive. this keeps the transmission from going into torque converter lock-up.
