The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

SOURCE: 1993 mazda mx6 transmission is not slipping, but will not shift into higher gears. Will run at high RPM's and not shift up. Any suggestions on what it might be.. Mechanical, electrical, fluid change,

SOURCE: 1998 ford explorer is having a transmission slip

Shift solenoid is typically WHEN to shift, not slipping.
Bands and fluid are slipping (and sometimes pump).

Cheap test, remove old, install new fluid... test.
If it works - congrats.
If not, AAMCO or other transmission place for a real test.

Heavy shifting


sometimes the shift sensors can go bad on these vehicles and would cause hard shifting in certain gears and would have to be replaced, a lot of times, going to a shop and have them run some tests on it would confirm more than likely a sensor. also, check your fluid... if it has never been changed, then it may be time for a fluid and filter change for the transmission, that makes a huge deal in it most times, also run a bottle of lucas transmission in there as well and it will help with any hard shifting and any slipping if it is not the sensor. hope this helps

You may need the transmission rebuilt, once it starts to slip that is the end in mist cases. Have a local transmission repair shop confirm my guess on this

My 92 toyota camry has power and all but it shifts hard wat could b the issue


Probably dirty transmission fluid and filter...you can use the ****** flush, or change the fluid and filter, or try the least costly...add one bottle of Lucas Oil transmission stabilizer fluid...(no not drain anthing) follow the instructions...warm motor, warm ****** etc. add the complete bottle...this works to restore the seals and shift points...All this of course assuming your motor is tuned and running smoothly...(clean air filter etc.) Hope this helps.

Shifts hard at first (when tranny is cold) then seems to shift fine. Checked tranny fluid level and it was low by a few quarts. Could this have been the problem or am I in danger?


this may have been problem[low on fluid] may be time to change that trannny fluid and filter. if you choose to do this , i recommend that you add lucas tranny treatment to the fluid change also w/new tranny filter. this frees up any sticky valves in your tranny. allows smooth shifting, and works well wlth any fluid for fords/chevy's or jeeps. the lucas will eliminate the hard shifting, been there done that issue. also the hard down shifting you did'nt mention. although you may have not noticed. add the lucas and your hard shifting issues should be gone. thank you for choosing fixya.com

Very hard shift from 1st to second, only appears when it is hot outside and engine has been running for a while. Any ideas?


Have you ever had the transmission filter changed and transmission flushed, That is usually the problem. If you did have this done already i would try running some lucas transmission fluid in it. You can find lucas at wal-mart.
