Shift solenoid-- Please help!
Hello everyone. I have a 00' 3.0 2wd ranger that is having some tranny trouble. My tranny sticks in 1st too long before hard-shifting onto second. When I get on the throttle farily heavy it will wind up to the rev limiter at which time I have to let off to get it to shift. Also, when it makes a reallty hard shift the "O/D off" light starts blinking. I'm thinking electrical, dealer thinks new tranny. Suprised? Me neither. Anyway, I take it to a friend of a freind who works at at tranny shop, and he scans it. Shift solienid B or 3 is giving a trouble code. I dropped the pan - no metal chunks to speak of - and replaced the solenoid, but I'm still getting the same problem. Now I'm thinking either wiring or connector problems in the solenoid electrical circut, or defective PCM. I have always had some strange electrical problems like guages filckering on and off, etc. Could the PCM be the source of all my problems. Any advise would be greatly appreciated.

Think you're on the right track - wiring, connectors, PCM, and don't forget the PCM ground which will cause all sorts of grief if intermittent. Try to borrow a spare PCM to swap in.
Another thing to check is the manual lever position sensor - this tells the PCM what gear range you've selected and has been known to cause problems.
One thing more - the throttle position sensor can screw things up once it wears out, since it controls shift points via the PCM.

Take it back to the guy that put on the solenoid.Pull the code again, write it down and then erase the code from memory. If its a wire problem it should set a code soon as the key is turned on, without driving it again. If its a connector, usually there are more than 1 code present.If it has to be driven to set the code and since the solenoid has been replaced, it must be internal slipage.Maybe you can drive it with the scanner hooked up and watch to see if the shift is being comanded by the PCM.
