36 transaxle shift control problem
Before I take it to the auto electric service place, can I fix any of these things on my own. If so I need some step by step instructions.
Can anyone help
In a nutshell, if those codes are accurate and reliable, your AC is shot (no pressure), your car lacks power due to a faulty EGR, and your trans has more than one problem.
Have the AC system repaired and recharged.
Clean your EGR valve with carb cleaner and a brush, let it evaporate, and then lightly oil the springs and shafts.
Get your trans diagnosed properly and rebuilt.
It would help if you would tell us your symptoms as you observe them. Some of these codes may or may not be current or even correct.
You might want to START by clearing the codes. Disconnect your battery for about a half hour, then drive for a day or two, and pull new codes using the trick listed in Techinfo. Let us know what current codes you have at that time.
