My Explorer has a little shifting problem, when it's cold it shifts fine like a brand new car would, but as soon as the engine warms up it shifts rough and redlines going through first and second. Are there any soulutions to this besides a Tranny Replacement? Thanks

Start simple first, Check your transmission fluid. If you don't feel comfortable with this, take it to a shop.

If this is a 2002-10 model explorer, here is the process:

1. Get vehicle high enough to access transmission drain pan (can be done on ground if you feel like crawling around under it) Be sure vehicle is level and supported by jackstands and jack.

2. Get transmission fluid temperature between 80 and 120 degrees F (a trip around the block) If you have an infra red thermometer with digital readout, use this here

3. Once fluid is in that range, with vehicle running, remove the center torx bolt from the transmission drain plug (NOT the big plug - there is a smaller torx bolt in the center of this plug)

4. Verify fluid level - If fluid pours out, it may be overfilled, check for leaks around seals. If fluid comes out in a slow drip, the level is ok. If no fluid comes out whatsoever, fluid is low, add new fluid as per directed in vehicles user manual.

5. Check fluid quality - If fluid is reddish, you are ok. If fluid is dark brown, black, smells burnt, or a combination of the two, you need to replace the fluid.

6. After checking level, replace torx screw and hand tighten, do not overtighten.

7. After driving vehicle verify there are no leaks.

Once again, it is critical the vehicle is level and transmission fluid temp is between 80-120F and the vehicle is running while testing.

If you'd like to know how to do a fluid change, respond to the thread and let me know. If you need to add fluid, you'll need a special fitting and pump to pump the new fluid up into the transmission.

I had the same problem but also had harsh reverse engagement when warm. Replaced the solenoid block and problems were resolved. It's a pretty simple procedure just messy especially if you do it on the ground. You should be throwing a code if the problem pertains to the solenoid block sticking.
