I just rebuilt my valve body with transgo kit. It said the K,B,Line pressure, and TCC solenoids should be between 5-7 ohms. Also they should not have any continuity between either terminal and the solenoid body. I had hard shifting when hot. After rebuild it's great. Maybe do the $100 kit on the old valve body and swap it back in.Valve body rebuild

I say try the Transgo kit. If all the solenoids test fine electrically as it says on page 2, step 1, you may still have problems with the armature sticking internally. That's what this kit addresses. I had hard shifting and flares. Many of the armatures inside the solenoids were slightly tight. The procedure to open up the solenoids, and clean them out (scrape inside bore manually by hand and clean with a drill bit) had a lot to do with the improvement as well as changing the valve body parts they supplied and drilling out the separator plate. I had ZERO faults in the computer before. Not one error yet it drove like **** after it warmed up. This fixed my problem. All my solenoids that get cleaned out tested within resistance specs and were not shorted to ground yet they were sticky inside. It was $100 for the kit. I borrowed a grinder from a friend to open up the solenoids. Read the instructions or give the kit and valve body to your tranny mechanic and have them do it. If you DIY, three cans of spray parts cleaner and A LOT of paper towels. A short, flat screwdriver is important to disconnect the wires from the valve body, they are harder to disconnect than it looked. Do follow the instructions religiously. double check each step before starting and completing. Making sure the wires are out of the way when dropping valve body and raising it back up are important. I used my floor jack to hold it in place. Carefully. I linked to a post/video in my previous post. Watch that video. Its a messy job but the results worked for me. I am preaching since the improvement was dramatic. If your solenoids test fine electrically, don't think everything is OK. They may still be sticky inside.

Wait. You tested the solenoids, they were good, AND you replaced them? WHY! For $100 you could have just done the Transgo kit and been done. Your symptoms are identical to mine. I fixed 95% of my issues with the kit. No more issues when hot, not more flares or hard shifts when warm. The only thing is occasionally the 1st to 2nd shift can be abrupt. Every other gear is butter. I can’t believe the you dropped the valve body and replaced the solenoids and didn’t do the kit. You were 75% of the way home.

Not exactly. Assuming you keep the original solenoids, the kit will have you disassemble them clean out the inside of the armature and the inside of the solenoid where the armature rides to create less resistance and faster, shifting reaction of the solenoids. Then you go into the valve body itself and replace a number of valves with either Improved design or lower resistance valves. Finally, you drill the separator plate in a number of areas to open up a number of ports that can become clogged and were undersized to begin with improving flow across the entire valve body. If you replace your solenoids, you no longer have to take apart the old solenoids and do anything to them. Since you have new solenoids, all you have to do is the remainder of the kit to replace valves in the valve body and the drill separator plate. A lot of what happens by replacing parts is also all the cleaning that you do to the valve body along the way, cleaning out debris, cleaning out little specs of material that could’ve been plugging up passages and restricting movement of check balls and little check valves, etc.

How is this going for you? My VB is starting to act up and trying to figure out a game plan

Just as good as when I did the repair. The only shift that is sometimes rough is the 1 to 2. All others feel normal. The 1 to 2 can be good and sometimes hard. If I accelerate slow and smoothly like I only want to get to 10mph then it’s shifts fine to 2nd. I have gone off-roading with it and it was great. I have over 10k miles since the repair and it’s overall totally fine.
