you should be able to fix it look for a can near the fuel tank that has vacuum hoses coming out of it and you should be able to just buy the bad solenoid

hi..the transaxle converter clutch . tcc. uses a solenoid -operated valve located in the automatic transaxle to mechanically couple the engine flywheel to the output shaft of the transmission through the torque converter.that reduces the slippage loss in the converter.reducing emissions.but check the vss first.which is called the vehicle speed sensor.they both work together .if the vss is not working right it wont call on the tcc.
check this out..

Here's a site to view what the part looks like, it's about $40. This info is assuming you have the 3.1 V-6, not sure if you have the 4 cyl. There is a charcoal canister that stores gas vapors so they won't be released into the atmosphere. These stored vapors are diverted to be burned by the engine. A defective purge solenoid valve won't allow the vapors to be burned, and the canister will eventually fill with gas. I changed one some time ago, and don't remember too well the procedure, but I believe it's just 1 or 2 bolts mounted on the upper engine area, I think it's on one of the valve covers, and a plug in (electrical). When you purchase the part, the parts store should be able to tell you the exact location. I remember the canister itself is under the coolant recovery tank. If you can see it (I seem to remember it was hidden) you can try to follow connections to the purge solenoid valve. Hope this helps, sorry to be somewhat vague, it's been a while since I changed it!

Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition ON and observe a voltmeter connected to the EVAP Canister Purge solenoid driver circuit at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP Canister Purge solenoid. A change in voltage will indicate the location of the fault.
The numbers below refer to the step numbers on the Diagnostic Table.
