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.

 

Trans Hard Shift and Slippage with Leak.
. I have To mention. If the little O ring in your transmission lines , the fitting, the hose, the crimps, whatever... are leaking...
. This can cause line pressure issues and is generally an easy fix..
Ive seen to many people throw a new transmission in their car then the same problem occurs or the transmission shop realizes they talked you into a transmission when it wasn't the problem... and then they stall you claiming they are waiting on parts while they are Frantically trying to figure out the issue. Once in awhile a Good Transmission Shop will Be Straight About the Costly Issue and work it out... but Far to often , Throw a Computer at it, Throw a Tps, a Fuel Pump, and Engine, a Rock, Light it on Fire... and it turns out... Bad Connection at the Battery, Bad, Ground, After Engine swap they forgot to add the Engine, Frame, Chassis, etc Grounds... or a Bad connector, bad wore, dirty ground to frame, leaky oil cooler and trans cooler lines, etc...
Take a step back and Start with the Basics.. Relax, its not the end of the world. It just sucks but it is an Adventure , a Journey, a Battle that once Conquered, Will Give You a Sense of Accomplishment, Education, and Comradery with those who Shared Their Knowledge and Time with You to Solve the Puzzle..

ok, Throw a Rock at Me... but I mean what I said. I met most of my friends because some Cool Car or any Car was parked with its Hood Popped... I would and still walk over and say Hi... and see if I can Help...

Note: Ford Expeditions and others... Route their Washer Fluid Line for the Rear Washer... RIGHT THROUGH the PCM and Bcm at the Passenger Kick Panel.. The Hard Plastic Line from the engine compartment goes thus far and then a rubber connector joins it to the Rear passing hard plastic line... When that Rubber Connector gets old and swells, cracks, rots, etc... It sprays Washer Fluid onto your Electronics and q number of other relays and grounds... This caused me some issues until I noticed a light blue stain on the front rocker panel to kick board channel... Thats when I realized and pushed the button... Washer Fluid spraying on my electronics.. That is Absolutely an Example of Built to Spill....
Done Rambling... Great Site....
