My Explorer has 221635 miles on it and has been a great SUV. About a month ago I started having shift problems. I got the codes from the vehicle and here is what I come up with. Code 629- Converter Clutch Solenoid/ Lockup Solenoid. Second code is 86- 3 and 4 shift solenoid Circuit failure and the last code is code 89-- Lock up Solenoid Failure. All three happened at the same time. Is it time to retire the vehicle? Is this a complete transmission failure and it needs to be rebuilt? Or are the solenoids something that I can replace. With over two hundred thousand miles on it I am not sure what to do. Body and interior are still good.
No this is not a complete trans failure this trans only uses those two solenoids so if it comes down to it replace those two which are in the pan. If all three codes came at the same time try running a ground strap from the frame to the trans, those codes do often occur with bad grounds!

your 98 ford explorer is a solid dependable suv. They do have a history of transmission problems so have your fluid and filter changed regularly I have an explorerer and a gmc jimmy and the ride and handling of the explorer is superior. You made a good choice
Sounds like you may have a vacuum line off or ruptured going to the EGR valve. The burning smell is probably the catalytic converter. When the engine runs rich you will get a sulfur smell that smells sort of like rotten eggs.
The first thing you need to fix is the fact that it will not go into park. I think the shift lever is maladjusted. There should be a way to adjust it near the transmission. Get this dealt with because I am thinking it could be a simple problem. If after you get it adjusted, it still does not immediately kick in to drive, then I think you have a serious tranny problem. You did not say how many miles were on the car, but if it has high miles (more than 100,000) and it has not ever been rebuilt, then it will probably need to be. The trannys in these Explorers were notoriously bad.
