Transmission stopped working ?

If the engine runs but does not move the car, it would seem to be the transmission. If you bought a car that doesnt start, it could be anything.

Charged battery, but need to replace. Jump started checked trans oil life 69 %. Waited to get engine warm. Put in gear car m over ??? Again ,prior owner stated he came to stop sign, car stopped moving. Now I don't know what to do or look for from here.

You could drop trans pan and see what oil looks like or have it towed to trans shop. How many miles on car?

Hello Everyone,
Just purchased a 2005 CTS 3.6, prior owner stated he pulled up to stop sign and car just stopped moving, had it towed to his home where it sat for about a year, then I bought it. Any idea what it can be ? Blown fuses? Control box ? Please help, any ideas would be great !
Thanks All,
Alan

I would start simply by looking at the coolant reservoir?

Is the fluid color nice and orange or is it a muddy brown?

I would also see if the tranny coolant lines going into the rad (bottom of rad) are wet looking any red tranny fluid on them?
This to me sounds like trans cooler failure.:canttalk:

Do what toms caddy says in checking the trans cooler lines for obvious leaks and if ok start with checking the tranny oil level so see if properly serviced.

Tom is correct, a lot of known problems with trans lines and coolers. Last owner could have had a leak. You wouldnt see it a year later. IF you loose enough fluid, trans would not move the car. There is no dipstick to check fluid level. There is a level plug on drivers side of trans. If you remove this plug, about a quart of fluid should come out. If not, you are low. Adding fluid may let you find leak.

Thanks guys, will check level and lines, also radiator, coolants. Car has 160,000 miles. 69% trans life, on oil, so it says.

Is that for the transmission? I thought there was just an engine oil life monitor; I thought the transmission oil was claimed to be good forever (hence the lack of a dipstick). Anyway, the 69% life is simply a calculation the computer does based on the distance and type of driving, so it has nothing to do with the fluid level and won't tell you if the fluid has become contaminated.

If no fluid comes out, the transmission was low. If fluid does come out, the level may have been fine, but now it is low. Either way, you need to refill it. muzikman does a good job of explaining the process in this thread.

With the vehicle running in park no fluid should come out at all. It's exactly like your differential once it comes to a slight drip coming out of the fill hole it is full. In my unfortunately extensive work with our transmission 69% life on the computer would really be about 30-40% actual fluid life (that is depending on your/previous owners driving habits) your fluid is probably going to smell burnt and discolored. Also if there is brown fluid in you coolant you would need a new radiator for it failed internally and the actual trans cooler lines may be okay still. Do your gear selector lights work on the shifter still?

Yes, shift lights work. Have not checked radiator. Car will go in gear, but, what caused prior failure? Car not registered, can't road test to see shifting.

After reading your posts, i have no idea if your car moves when you put it in gear?
