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.
