I have a 1993 Buick Lasabre and I need to have the transmission replaced, can I replace it with a 1994 or a 1995 transmission. Thanks.

unbolt mount from transmission while supporting with jack. Jack up slightly. Unbolt old mount from cross member. Replace in reverse order, do final tightening with jack removed. A few vehicles require the cross member to be removed from frame to access the lower bolts/nuts.

replace the springs,they control the ride height.......

from the front of the engine.....
1...2
3...4
5...6
firing order 135624.

Coil pack sounds to be bad.

your gauges need to be replaced it sounds like you have a bad mother board on it.

Transmission filter needs changed or the Transmission Needs Serviced. I would take it to a service center.

yes the year models 93 through 99 should all work

The balancer will have to come off, you will need a puller to remove it. Also you will need an air impact wrench to remove and replace the big bolt first.

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.

check your alternator it might not be charging
