95 Explorer Hard 1-2 Trans shift -HELP
I have a 95 Explorer, 4.0, AT, 4x4, 198K miles. It will not perform the 1-2 trans shift without letting up on the gas when the engine gets to about 3k RPMs. I don't think the trans has ever had any maintenance done, so I'm very leering about having a full flush done on it. I am considering dropping the pan and putting in a new filter kit. I'm looking for thoughts and opinions on this. A rebuilt trans is completely out of the question due to the overall condition of the truck. Please send me your thoughts. thanks

This sounds like you have a blockage in the trans that is constricting the flow for that solenoid to shift properly. You could try to get a shift kit for it to clear up the flow as well as a flush. Sometimes a flush CAN help. Do a fluid and filter change too. Hope that helps.

You can get them at most automotive shops or speed shops. I am not familiar with the install but I am sure that it is pretty easy if they sell them in standard stores like Advanced or NAPA. If I am not mistaken it is a bolt on application. You are replacing the old oil pathway plate with the new one. Not too sure on the actual dynamics for I don't usually work on Automatics. Check with your local trany shops for more info. They should be able to help you on that. But from what you are describing it sounds like a blocked pathway or maybe a solenoid is going bad. It would be different if it did it in all gears but this is pretty specific. The stall rate is getting too high for normal shift meaning the solenoid is not working or the pressure is not high enough to allow it to shift right which causes the Converter to spin higher to build up more pressure. If it did it in all gears then it would be the Torque Converter but this is in a specific gear which leads me to believe it is the earlier.

95 XLT, 4.0, 4wd: I pulled a 646 code (Transmission 2nd gear failure) which makes sense since my problem is the 1-2 very hard shift. One other thing to add is that the OD light is blinking as well. This all started at the same time. Based on some of the posts on this forum, I'm leaning towards adjusting the bands. It's my understanding that the 4R55E has 2 bands, an overdrive band and an intermediate band. Here are my questions:
- specifically where are these bands located? I know they are external to the trans.
- which one controls the 1-2 shift?
- what is the adjusting procedure?
- what else do I need to know in order to not mess this up??!!
