Hi there:Its possiblke that you have the solenoid replaced for the code with out having a test of the system 1st? Also you could still have a bad new part.
This is the check needed to find out what is going on HERE.

Hope helps.

They are located inside the transmission. Would be best to have a shop do it. There are a lot of small parts inside the transmission and there maybe something else that caused the malfunction in there too.

Engine codes for a 1998 plymouth voyager

okay, 1998 voyager these are not obd2 codes, these are genric codes, you used ignition to get these .
these codes are for older models that use codes like these 12 35.
the newwer obd 2 use codes like po 013. i will try to see what i can find, also the engine size is important.

okay here we go, the first code is 12, this code means the battery was dead or dissconnected.
the next code 35. this code means loss of prime, code # 11
means internal transmission failure.
the code 55 means gear ratio error.

these codes would tell me that you have transmission problems. this may mean internal trans failure and a rebuild or replacement transmission is needed or shift pack needs replacing. anyhow i would have a shop check this out, these van are known for transmission problems. hope this is helpful good day

Car has problem starting because the check engine light is on and when placed on the diagnostic machine the follow code appears PO773

I copied this from the on the P0773 problem, but I do not think that the solenoid problem it calls out could cause the car not to start. Have you taken it to a auto parts store and had them read the codes for you. It is usually free and they will explain them also.

Background (from the FAQ thread):
Solenoid E (SL) is the torque converter lock-up solenoid. If the torque converter is a little slow locking up, it will set a P0700 code.

The ECM compares engagement condition of TCC with lock-up schedule in memory to detect MECHANICAL trouble of lock-up solenoid, valve body and torque converter. (The P0773 trouble code is probably from monitoring electical signal to the solenoid. Might be worth checking the electical connection and wiring before you replace the solenoid) A P0700 trouble code is set when TCC lock-up does not occur during appropriate speed, or lock-up does not release at appropriate speed.

There are simple electrical tests to check the solenoid and plunger but the transmission pan must be removed to gain access.
A Toyota service tech can check the system without pan removal with his analyzer.

Keep an eye on the rpms when you are above 50 mph. They should be constant at constant speed, like in a manual transmission since the torque converter is supposed to be locked up above this speed. If the torque converter is not locked, then your mileage will suffer, and your tranny fluid will heat up above normal temperature. If you use synthetic fluid, you will minimize the problems from overheating the fluid. The life of the fluid will be shortened in any case if the torque converter doesn't lock up and you drive at expressway speeds, particularly in hilly country.
