If the transmission is not shifting, could it be the vaccum modulator?

The trans missions was shifting well but noticed going into overdrive acted like engine had a miss. I changed plugs and wires and no change. then just other dau i noticed it starting out very sluggish, like starting out in high gear. I manually shifted and seamed to shift ok. Could it be a bad vaccum modulator?

When was the last time the tranny had a new filter put in with new fluid? if the vacuum module was bad, it would suck all the tranny fluid out of the tranny and into the engine from vacuum and you would be smoking out the tail pipe..

The OD solenoid in the transmission or the transmission control module is defective. It's also possible the torque converter clutch plates are worn. That's where over drive comes from

Trans


replace the Vehicle speed sensor (VSS) on the transmission, it senses when trans should be shfited to overdrive by the Transmission control module.

92 ford explorer. runs great. replaced vaccum modulator recently. shifting from park to drive the engine revs up ( 60% of the time) and its like in neutral. then i shift back into neutral and wait till...


Sounds like the filter in the trans is plugged up. Should flush trans every 45,000 miles and replace filter and fulid. Its easier to take it in to a shop and have it done they use high pressure flush which will clean out the whole thing for about $200.

Transmission problem


it is not a main computer problem but the transmission control module. the engine speed sensor sends a signal to the main computer(ECM) which then in turn sends the signal to the trans mission control module. the cost of this can be pretty steep if you go to a dealership, however if you go to a local parts place like Napa the cost will be half. one last thing to check is to have a diagnostic scan tool hooked up this will tell you what codes are showing and i'm sure there are some. ythey will clear the codes for you. also if a solenoid inside the trans mission is the problem and sometimes they are because of gummed up fluid they can replace it for even less.. hope this helps...please rate this thanks
