Any transmission smart guys here?

[vossman]

I have a 02 Saturn SL1 with 130,000 on it. Auto transmission shifts funky from 3rd to 4th and 4th to 5th. Revs will spin up a few hundred RPMs them clunk into the next gear. This used to be infrequent but now it does it all the time. I refuse to drive it to work as I am sure it's gonna take a huge shit on me then I'll be stuck. The trans shop I took it to said they found nothing wrong, then I took it to my regular shop and they said maybe electrical so they replaced the spark plugs and wires. They said they will continue to troubleshoot if I want them to but I thought I'd ask here.

Spark plugs and wires?
Your torque converter could be going out, your valve body could be having problems, your solenoids could be taking a shit, but its not your plugs and wires. It sounds like a solenoid problem to me but i do not know much about your transmission. I hope someone here can help you more.

Last service date, with converter flush? If you don't know, or remember it's 60K over due. The shop that changed your plugs and wires, should be taken off your repair shop list.

Did the trans shop do a pressure test? There was an issue years back with seal leakage between 1st / 2nd and reverse. 2002 saturns were known for valve body issues. Unfortunately the cost to repair is as much, or more than the book on your 02.

A number of auto trans have two internal wet clutch packs or bands, one for 1st/2nd and one for 3rd/4th and reverse. Does your car have any issues in reverse that are similar to the 3rd/4th issues? If it does I would think internal tranny repair/replace issues.

It's more than likely only a 4 speed by the way.

any DTC's, maybe a P1811?

[vossman]

No codes, no engine light.
I changed the fluid and filter today and I think it got worse. I will limp it to a shop tomorrow and see what they say. The car is worth about $1k so anything more than an adjustment will probably mean it gets sold for scrap. Not sure what else I could do with it.
