Wonky Transmission trouble
Can someone offer some insight? I've got a 2002 Dodge Stratus with a transmission fluid leak. Shop said it was the solenoid pack. They replaced it with aftermarket solenoid. After two weeks, transmission started going into safety mode (the built-in mode where the trans stays in second gear) and engine light comes on. Took it back to shop, they put in another aftermarket solenoid. Same result, i.e. two weeks fine, then safety mode kicks in and engine light comes on. Took it back to shop, they replaced solenoid with a new dealer solenoid. Same result, i.e. two weeks fine, then safety mode kicks in and engine light comes on.
After the first failure, I went to Auozone to get a free Fix Finder report to see what the OBDII codes would say. The two errors it found were P0700 Transaxle Control Module Malfunction and P0846 A/T 2-4 Pressure Switch Circuit Malfunction.
Before I go back to the shop a third time, I'd like to gain some kind of insight into WTF is going on. If the solenoid isn't the problem, what else would fit these symptoms? What advice (besides dumping this particular shop) would you offer based on the behavior and OBDII report? Thanks.

Pressure sensors are built into the solenoid pack. Wires run from the solenoid pack directly to the separate TCM module in 2002 year cars with an inline connector.
Now you don't have to touch the TCM or the inline wiring connector to replace the pack but you do have to touch the wiring and connector plugging into the solenoid pack and scrape off old gasket material on top of the opened up fluid ports leading straight into the transmission.
So we can almost certainly conclude the problem is either a bad connection with the 2/4 clutch pressure switch circuit OR they dropped gasket material debris into the transmission and it's restricting fluid flow to the pressure switch. Also as a side note, the any transmission shop should be able to check your CVI values of the clutch packs so, make sure the 2/4 clutch CVI is within spec just for good measure.
Good luck.
