I recently bought an automatic 1994 Ranger and the check engine light has come on. I pulled codes (KOEO) and got 629 and 566. Looks like 629 is torque converter solenoid/circuit failure and 566 is 3-4 shift solenoid/circuit failure.
Thats great and all, but how can I determine if these solenoids have actually failed or if there is a circuitry issue someplace else? Any suggestions would be great...I'd rather not get screwed out of hundreds by a shop to replace these parts if it is something much simpler.
