I just had mt transmission serviced on my 2003 ford taurus changed the fluid and filter the trans,had no problem before .Now with new fluid and filter it does not go into gear....
changed fluid and the old filter.
Hello and welcome. My name isXXXXX will do my best to answer your question satisfactorily.
First off, can you tell me was the service done at a shop, or did you do it yourself?
How long after the service did this problem begin?
Are you interested in repairing this yourself?
Thanks in advance.
I had it serviced at a shop I was right there the mechanic just droped the pan and removed the filter and sealed the tranny back up put new fluid it it ,now it does not shift.
Did this happen right away or was the car driven a while?
Are you able to check the fluid level? This should be done on a level surface with the engine running and transmission in park.
The first post states the trans will not go into gear. The second says it will not shift.
Are you saying that when you first place the gear shift into drive or park and accelerate the vehicle does not move, or that it starts out in first gear and will not upshift to second.
The car does revs.up but does not go into drive or reverse
Ok. There are 3 possibilities here.
03-04 taurus/sable/windstars have common failures of the torque converter. This is something that needs to be diagnosed hands-on by a transmission mechanic.
The second possibility is that the fluid is low and the pump is unable to produce any pressure. With the engine running, vehicle in park, and on a level surface, remove the transmission dipstick located behind the intake air tube that connects the air filter housing to the engine. Wipe the stick off, insert it again fully, then pull it out and make sure the fluid is somewhere in the hatchmarked area on the dipstick.
Third and possibly the most likely scenario is that the transmission filter has fallen out of the valve body and into the fluid pan. There is a rubber seal on the filter where it is pressed into the valve body and this is the only thing holding the filter on.
To check for this, the transmission fluid pan needs to be removed.
If you find the fluid level is ok, the next step is to remove the trans pan to inspect the filter. If the filter is secure, then the problem is either the torque converter or an internal transmission failure, either of which will require the transmission to be removed.
Thank You James ,but how is it there was no sign of failure before from the converter
Thank You James .how come there was no sign of any problem with the converter before the fluid change,the transmission was shifting normal ?
Start by checking the fluid, then the filter as we discussed earlier so we don't get ahead of ourselves.
The issue with the converter is that one of the internal pieces breaks off cleanly due to poor welding. Both halves of the broken part are held in place by the rest of the converter so it stays in position, but won't turn the fluid pump.
Most often, when this failure occurs inside the converter there is no noise or warning whatsoever. People report coming to a stop while driving, then when they try to accelerate again the trans neutrals out. Sometimes is happens first thing when you get into the car.
There is no noise associated with this as the converter is full of transmission fluid which deadens any sound that would have been there.
