TRANSMISSION TORQUE CONVERTER

1999 Cadillac Deville

Transmission problem
1999 Cadillac Deville Engine Size unknown Two Wheel Drive Automatic 92,000 miles

About a week ago my husband was driving the car and he said he was going very slowly and l" ost steering" and ability to accelerate. He thought the engine died but once he got it off the road somehow and tried to restart it it made the sound cars make when you try to start a car that is already started.

The next day, I was driving the car. As I was stopping at a stoplight, the car died.

I took the car in today to the dealer and they said the transmission torque converter needs to be replaced. They said they weren't sure if that was the problem but the computer wouldn't let them go beyond this. They said there could be a vacuum leak somewhere but that they couldn't find one.

I was told almost 1 1/2 years ago that the transmission torque converter was going bad but recommended not to replace it at that time.

Another confounding issue: Last summer I let the Valvoline Quick Oil Change place change the transmission fluid. Immediately after that was done I had the car stalling when coming to a stop. The valvoline place had taken apart and removed a part to get to the transmission and when I brought the car back they replaced the part that connects the two parts. (I could point to the part if we were looking at the engine together but I am car ignorant and don't know what the part is called or exactly what the parts are it connects. Sorry) The tubing was completely broken away from the part and was causing a vacuum leak.

After that was fixed I had one stalling about 6 months later.I was slowing down but was on a small highway and not close to being stopped.

So, I am reluctant to spend $2300 to replace the torque converter if that is not the problem. Or if it is, is there something like a good cleaning and maybe replacing the cellenoid that I saw referred to in a couple of letters that might fix the problem?

Scan your codes for me, push off and warmer buttons on the heater controls at the same time, with the key in the on position, look at the insterment panel in the message center for the codes. Write them down and post them here!

A ck engine light would come on if you were having trouble with the trans, or a message in the message center in the IP ( stands for Insterment Panel)

I would say that the stalling is from your crank sensors, but scan the codes first
