Thanks for the pic it was very helpful i changed them it helped a lil but the plug for the epc solenoid isn't pluged in all the way i tried to plug it all the way in but it wasn't going and i wasn't forsure if it was actually like that but my truck won't shift at all now it pulls out in all the gears but it won't shift could this be the problem where the epc solenoid isn't pluged all the way in???

It has to plug in completely.

 

[firefighter241]

ok i pluged the wire competely in but now it won't shift it pulls out great and like when i downshift u can feel it go down a gear but when u shift up u can't feel it kick in or anything could u tell me what my problem could be now

 

[BrooklynBay]

How many miles do you have? Maybe the EPC is no good?

 

[firefighter241]

I just had my truck put on the computer it says solenoid 1,2,and 3 is stuck could that be the wire harness shorting out or something?

 

[Glacier991]

What was the powertrain code you pulled? That will help me a lot.

 

[firefighter241]

Am not sure what the code was the guy didn't tell me but he told me the solenoid 1,2,and 3 was stuck.
But when i changed the solenoid the other day the wire harness was bad could that be the problem just by a guess could the wires be shorting out or something and not gettin power to the soloenoids

 

[BrooklynBay]

It sounds like the harness.

 

[firefighter241]

I just got the wire harness in i know how to hook all the connections up just the main one can u explain or send me a pic how to

 

[BrooklynBay]

You want to know how to clip it into the housing?

 

[firefighter241]

ok i found out how to install the harness but i had it put back on the computer and it is saying the solenoids is gettin stuck here is the codes
po751
po755
po756
po761
could somebody tell me why they are getting stuck

 

[BrooklynBay]

These might be codes which are stored in the computer's memory from the previous harness. Clear the codes, and see if they come back again.

 

[firefighter241]

Ok i'll do that but if the codes isn't erased would it still affect my transmission because when i go to pull out it won't shift into 2nd unless i let my foot of the gas and it changes and then it won't shift into od which is about 60 or 65mph

 

[BrooklynBay]

The computer probably thinks that there is still a problem, and is compensating to prevent overdrive from applying.

 

[firefighter241]

Ok i got all the codes erased on my truck and it is still doing the same thing which is i have to let off the gas to let it change into 2nd and it won't change gears when i hit 65 or 70 what else could be making it do that?

 

[BrooklynBay]

Check the band to see if it's broken.

 

[firefighter241]

what band are u talking about ?

 

[BrooklynBay]

The middle band is the intermediate band for 2nd gear. The first one is the overdrive band.
