Question about Cars & Trucks
I have asked three mechanics and a parts store before I spend a lot of money on my truck
You really need to have it on a scanner. When you take off the shift solenoids come on and shut off at different gears. 1st gear is both are on, 2nd gear is off- on, 3rd gear is both are off, 4th if on- off. This is where the scanner comes in, to see if the ECM is commanding the transmission to shift. Plus to read any codes. Also with the scanner you can command the solenoids on and off and listen at the pan for clicking noises. If they are good, then you have to look at the valve body. First pull the pan off and see how much metal is on the bottom of it, If there are any chunks of metal, I would rebuild it. If it's just the usual fine material, clean it out, replace the filter. I would also replace the EPC(electronic control pressure solenoid). They get clogged up and could cause your problem. Don't try cleaning it. It's waste of time and you would be taking it back out. When refilling the transmission, I would add a bottle of additive, Tranx, lucas, or whatever you prefer. Make sure you get an EPC solenoid that is exacly like yours, threre are diffenet ones out there that will fit in it's place, but won't work.

More likely you have a bad transmission but there is a few things you can check that doesn't cost anything but time.
1. First (Set Parking Brake!) make sure your linkage cable from the shifter to the side of the transmission is actually moving through the gears by having someone shift it while you look. If you need to you can unhook the clip that holds the shifting cable and remove it by placing a small screw driver. You can move the lever all the way forward and the truck is in park.
Pull back one click.. reverse
Two clicks back...... netrual
3 clicks back is ......... drive
All the way one click at a time will take you down just like the letter on the gear indicator on the steering column.
If the cable is working correctly then you have a bigger issue.
Probably easier to call a junk yard and buy one for about 2 to 500 bucks.
**Possibly shift solenoid coil unplugged or bad connection. I had mine do this too. I took the tranny pan off and found the solenoid coil wire broken. Took off the nut and slipt the solenoid off and cleaned and solder the wire connection back on. It was hit and broken during a filter change but didn't breaklater. Could be the bans too but usually that is shutter and slip. paying someone 2500 for a tranny job is crazy. More than likely you can find someone on Craig's list to do the transmission change out for under $500 labor plus parts. Call a salvage yard yourself and have them deliver the transmission so you know what you gett
