Arriving from Saturnfans
It has only been a few days since I have been unable to access Saturnfans.com, but when my car is inoperable, my sister has nothing to drive. (it was a mistake to agree to share, I rarely see it) It is operational at the moment, but you can never be too prepared.
My car is a 1999 SC1, with the "third door" flap. It was originally grey, but the hood, and bumper cover are now blue after a minor accident. It is now on its third automatic transmission in 2 years. Very fun to drive compared to my parents modern SUVs. |
Welcome.
Do you have a question? |
The transmission lines and cooler need to be flushed when replacing the transmission. And if you're using the old torque converter, DON'T. It's probably full of crud and debris and you need to put a NEW one in when you replace the transmission again.
|
What is the current problem? Tranny again? As noted above the swapper needs to do the flush. TC can be flushed but a replacement is best.
|
I did need to replace the torque converter at some point, because it failed, but how would it get full of crud?
|
There does appear to be a current problem with the tranny, the last time I drove it, it was slamming between what I assume are 1st and 2nd when pulling away from traffic lights. I will need to look at that when I address the loose steering shaft. It is loose on the steering gear where it slides over it just after the last U-joint, causing excessive play in the steering.
|
The torque converter pulls the fluid through the transmission. The fluid is sucked into it and it spins and makes pressure that helps push the fluid through the valve body and change the gears. You should really do the research on your own. I'm trying to simplify it, but I don't always come across clearly. I'm brain damaged.

I always thought it was the transmission oil pump that built pressure, but I guess the torque converter probably does have something to do with it...

Thanks for the explanation, Gary. That makes sense.
