Question about 1995 Cadillac Seville

1 Answer

Transmission Shifting Problem, 1995 Seville with Northstar and approx. 70,000 miles

"Service Engine" display has been staying on most of the time. Coinciding with that display the transmission shifts abruptly. A transmission shop said "your transmission is broke. It'll cost you $2,000 to repair. Since the problem doesn't always appear could there be another problem such as a poor electrical connection external to the transmission.

Another problem has been difficulty moving the shifter from park. As of this morning (6/21/08) I have not been able to shift from park at all so the car sits helpless in my garage.

    Because of high gas prices I haven't been driving the car much; however, I still need the car occasionally and would like to use it if repairs are reasonable in cost (In my present situation $2,000 isn't reasonable.). Could the two problems I mentioned be two symptoms of one problem rather than separate problems?

Can vacuum leak affect transmission up shifting? A cracked vac hose? 4.1 V8 FWD. Throttle Body Fuel Injection.

run the fault codes first to check for TCM or servo/solenoids faults
the actuator is vacuum operated so a broken/ missing hose will have effects on gear shifting

Why is car abruptly jolting to a stop in reverse and not moving?

Sounds like the transmission is shifting into both reverse and a forward gear at the same time. Time for a tranny overhaul. But first check the transmission fluid level.

97 caravan check engine light, transmission will not up shift from 1st.

The only reasonable part is the labor charge. I couldn't second-guess the shop's recommendation, maybe both parts are needed, but you could have them replace the shift solenoid, and try driving it for awhile, see what happens. Then if you need the TCM, try a used one from a salvager for less than half the cost of new. That is something you could install yourself.
Whatever you decide, good luck.
