Question about Ford Explorer
My transmission (5R55E) in my 99 Explorer will not engage in any forward moving gear. Reverse is fine. Prior to losing all forward movement the transmission was slipping between 2nd and 3rd gear. Then for a bout 2 weeks it would not engage for the first few minutes after i started the truck up and then finally no engaging in 1st, 2nd, D, or OD at all. I replaced all the solenoids (EPC, TCC, and all 4 shift solenoids) on my transmissions valve body and the gaskets that were visibly blown (common on the 5r55e transmission) but the problem persists. Should I shift focus to the GEM or is it more likely that my transmission itself has more issues?

SOURCE: Heres the symptoms : engages
it may be a bad transmission modulator valve located on the side of your transmission,vacum operated. a sudden downshift or forward shift when unexpected is sign of a bad modulator valve or a vacum leak to the transmission.best to shop around for a garage w/references when it comes to transmission work though. check all the vacum lines to your transmision,you need to look on the underneath side of your truck on the side of transmission for a loose or disconnected vacum line on the side of the transmission. when you feel the vacum line,follow it to the top of engine,the vacum line is about 3/8th line,and may be disconnected or losing air. to make this short,when you drive the car,start out in low gear and shift the transmission,manually from 1st to 2nd to 3rd does it do right with no slipping? if it does this right and shifts great manually,the modulator valve on the side of the transmissions bad,or a bad vacum leak in-between.thank you for choosing fixya.com

My guess is the cable needs adjustment on the shifter.. seems to have slipped maybe a loosened hold down bolt..these have to be precise, good luck!!!
