I'm sure you all know by now I'm having transmission problems.

After doing much reading around and talking to people

I have really started to think my epc sensor or valve in my transmission is bad. From the symptoms other people have been having because of their epc sensor going(slipping,hard shifts,no gears at all)

Im having slipping and hard shifts.

Does anyone think it could be that? Is there a way to test it? And how had is it to replace it...the thought of spending 3k right now sucks.

Thanks in advance.

 

what does the epc stand for

 

There is no EPC sensor. There is an EPC solenoid. EPC means Electronic Pressure Control. This solenoid controls pressure in the transmission.

There is a test port on the side of the transmission. The shop manual has expected pressures for each gear. You need a 0-400 PSI gauge to check it.

 

thanks for the info mark sent some reps your way

 

Sorry mark, that's what I meant. I was just in a rush to list it.

Mark, would you know it it's hard to change out or not? I'm sure I have to drop the pan?

Would that make sense if that's bad it could be causing my problems?

 

Also, I believe my TC is locking up.

Sometimes it feels like I put the truck in park but I didn't. Then I really have to hit the gas pedal then it feels like it breaks free. Then it fine

 

I also scanned it and got no codes.

I'm lost.

 

anyone want to give me anything?

I am going to order a new TC soleniod. Thanks to Bismics, break downs.diagrams I think I can replace them myself.

Should I order anyother ones? Due to the hard shifts in first and second?

 

Everytime I've read where someone changed a solenoid it didnt help. Save the cash and get a new tranny. that way you also have peace of mind.

 

You've probably checked theses basics Allready but.. Any sparkled in he tranny fluid on the dipstick. You could pull the cover off the torque converter and check for end play and broken flex plate (not likely but quick) metal in cover. And drop pan and check for small parts and shavings/sparkles here. Are you FWD? Might try shifting 2-4 and try to determine of it is xmsn or xfer. I suspect leak you mentioned earlier is the best clue though.
