The River 1982

I was told today by my mechanic that one of my shift solenoids is either stuck open or broke causing my car not to shift from 2nd gear to 3rd gear. He told me that I should have my fluid and filter changed and replace one of the quarts of transmission fluid with Trans-X. I am just wondering if anyone else has had this problem and also how much it costs to have a solenoid replaced. Thanks in advance!

The solenoid repair may cost a couple hundred bucks including a new filter and fluid since you need to remove the pan to get to the solenoid. I also recommend that once it is repaired that you put only the fluid recommended by the manufacturer back into the transmission. Check the transmission dip stick for the proper type.

Are instructions listed in the Haynes or Chiltons for replacing the 3-4 shift solenoid...does anyone know of any tips or tricks to performing the replacement on your own?

Replacing any of the solenoids in a 4T65E tranny is not an easy job and not classified as DIY. That solenoid along with PCS, TCC-PWM, and the 1-2 upshift are located under the tranny side cover assembly on the driver's side of the car. The ATF must be drained. The air box and PCM have to be removed along with everything in the way. The driver's side axle half shaft will also have to be removed which means just about everything on the driver's side wheel. Also you will need new side cover gaskets and the side cover bolts must be properly torqued to specifications upon re-assembly.

Typically, a tranny shop will probably charge around $400 - $500.
