Just like the title says its having troubles, Its almost like its stuck in second gear, If I take off when cold it shifts from first to second just fine but it wont shift from second to third and its also upshifting and downshifting at about 50 MPH it upshifts like its supposed to then downshifts and keeps doing that I dont know whats wrong Im good with motors but trannys are another story. is there a sensor or could it be a bad shift solenoid?? Do the 94s have the D4U1 upgrade in them. I also heard about a little c-clip that falls off or something. PLease help.
