Bad design flaw with the transmission kick down cable make sure you are in OD first but if you are then this cable is adjustable it is next to the throttle cable and tells the trans when to downshift only adjust very little increments as this can easily blow your tanni as you may already know this feeling

When 1994 lincoln continetal is warm will not shift into second or reverse


The transmission is failing.
Check fluid for level and quality. If level is low, add transmission one pint (16 ounces) at a time until the level on the dipstick is correct. If the level is good but the transmission fluid is dark in color, tan in color, watery, or obviously burnt, start by having the transmission fluid and filter replaced.

My 2001 grand marquis hestitates and shutters slighty when downshifting from 4th to 3rd gear, shutting off overdrive eliminates problem


The first thing to do here is to have the transmission fluid changed, the shudder is torque converter clutch chatter, just like a burned clutch in a manual transmission car. The new fluid renews the anti friction additives and in most cases eleiminates the problem, have the transmission flushed so all fluid is replaced.

The transmission is hanging up in 2nd gear and not shifting to 3rd, 4th etc. It does not downshift to 1st when the car comes to a stop. I can manually downshift to 1st, upshift to 2nd, but it will not...


The absence of 3rd and 4th is imposed by the transmission computer as a precautionary measure. The system has detected fault and rather than risk doing any greater damage has provided a limp home service. It needs to have a transmission specialist look it over and read the error codes. How do your transmission fluid levels look?

Transmission defects in downshift


With any manual transmission you shouldnt just go from 6th to 4th bc it is bad for the transmission, if i am in 5th gear and i want to go into 3rd i always go from 5th to 4th to 3rd as a preventative maintenance. If you have a defected transmission you should be able to get it warranted by the bmw dealership you bought if from though.
