4r100 post flush abnormalities
OK, I had Ford flush my transmission with 130,000 miles on it. I had reasonable expectation/ proof that tranny had been serviced at roughly 80,000 miles. Other than being told that the fluid was low probably due to the rear trans to transfer case seal leaking (high level in transfer case) everything went smoothly. Except.....
The next day while keeping rpms low and driving, the 2nd to 3rd shift acted very funny and pretty much shifted into 3rd then immediately into OD, then into 3rd etc...until I let off the throttle. I paid very close attention and couldn't make it do it again. I thought well, I probably moved a small piece of trash through the system no big deal. Now,
when backing up my driveway (50 ft) on an incline, if the rpms are low it will buck and chatter. If you give it gas and accelerate more aggressively, it will back up smoothly. Any idea on key problems to search for? I have come to a dead end on internet searches. I am actually looking for someplace to backup on an incline repeatedly hoping to "work it out". Any words of wisdom are greatly appreciated. And if you read some of the other forums, I am sorry ahead of time for any duplicate posts. Some people only read one website and I want to get as many opinions as possible.

It isn't going to "work it out." It's low on fluid. Warm the trans up and check the level while idling in park.
Did they change the internal filter? It may not be installed right, or they may have used a filter from a 4x2 E4OD. Those have a shorter pickup tube and can suck air.
