Ford 2001 explorer sport transmission slipping 2nd to 3rd gear
Noticed recently when shifting that rpm jumped fro 2k to 3k prior to shift. changed screen and fluid. noted no metal shavings or debris in pan. new screen and fluid did not resolve problem. I did notice that one of the four shift solenoids was a bit loose as compared to the others.

VSS. Vehicle speed sensor. Although Im sure its already been done but check the transmission fluid. Change it out with new fluid and a filter if you want to and when you do, look at the old fluid and see if its blackish or not pink/red. Look for metal shavings in the fluids catch pan and in the transmissions pan and in/around the filter. The small stuff 1st. Then you can rule out that and move to the bigger stuff.
check transmission fluid levelif you see metal shaving in oil pan time for rebuilt if you see more than a table spoon full of shavings but i would change transmission fluid and filter.if engine running higher rpm on acceleration transmission is slipping.
P0756 FORD - Shift Solenoid 2 Performancehttp://engine-codes.com/p0756_ford.htmlForum CodePossible causes- Low transmission fluid level - Dirty transmission fluid - Faulty shift solenoid 2 valve - Shift solenoid 2 valve harness or connectors - Shift solenoid 2 valve circuit is open or shorted Help with thisTech notes When the a transmission solenoid is stuck off, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced.
First thing you will need to do is change the transmission fluid and filter. You may have metal shavings inside your transmission pan blocking the filter kit and this would cause your vehicle to skip gears. Try installing the new fluid and filter kit first. Since you will have the pan off, replace the A and B shift solenoid if the new filter kit and fluid don't stop your transmission from skipping gears
I have been hearing a possible solution for this problem is changing the oil filter in the trans oil pan. But ive been looking all over for a solutionand thats the only legit one ive found. It said when the oil gets clogged it doesnt flow to the transmission as nicely as normal therefore leading to lagging changes
Try changing the transmission fluid and transmission fluid filter. It is a fairly easy but kind of messy job. Just buy the new fluid and filter, Grab your metric socket set and go at it. NEVER WORK UNDERNEATH A HOT VEHICLE. You have to pull the transmission pan to do this job. When you break the gasket seal several quarts (liters) of transmission fluid will cascade down on you. Be ready for it. Don't forget that when it stops draining there is still a lot of fluid left in the pan. When you finish cleaning up the fluid clean the gunk out of the pan. Install the new filter and reinstall the pan with a new gasket. Do not over torque the pan or filter bolts. If you strip them out or break them off you will need professional help to repair it. Refill the transmission with fluid. It should take six or seven liters.
The only hope you have of saving your transmission is to change the fluid filter in the transmission pan underneath the van. You will also need to add new fluid to the proper level when the filter is changed and the pan re-installed. DO NOT USE ANYTHING OTHER THAN FACTORY-STYLE FILTER AND DEXRON III FLUID. DO NOT USE ANY KIND OF LIQUID TRANSMISSION REPAIR UNLESS YOU HAVE 3 GRAND IN YOUR POCKET. And it still may come to that, most likely will. You have described a dead transmission. If the fluid in the pan smells rank and burned, is dark brown and gritty, or has visible metal shavings in it, the transmission's toast.
I need to know the codes so I can properly diagnois your problem. Here are a few tips though. Your electronics inside the transmission may be going out. You should start by changing the fluid and the filter. Let me know if there is a lot of metal or fiber shavings in the pan. Put new fluid in and clear your codes. See how it shifts and then let me know what is going on with it. Hope this helps.
slipping or flairing between (during shifts) is usually the result of internal seal failure inside trans. you can check fluid level, and / or change trans fluid... if changing, any excessive metal debris or non metallic flakes in the pan indicate need for rebuild. Shifts are controlled by solenoids not by vacuum.
