The 5hp may be cheaper to do. I have a 6hp with the A051 plate. Apparently they're becoming rare. Most places are only rebuilding them now rather than outright selling rebuild units. Why are you paying a shop to drop it. So it yourself. It takes maybe 30mins. Drain fluids. Drop the pan. Pull the mechatronic locking tab. Turn mechatronic sleeve to unlock/unscrew electronic plug. Remove plug. Unscrew valve body bolts and lower valve body. Let it all drain. Dry off. Remove TCM carefully. Pack in about 3 bag. Package and mail off. Sent from my iPhone using Tapatalk

Unless you are sure what the problem is, since a transmission shop is pulling the transmission, I would have them do a diagnosis before they pull it and you start buying parts.

Ahh. Ok. Gonna have the whole thing rebuilt? You may not need it tho. The transmission itself is pretty solid. From talking to many rebuilders, the impression I get is worn valvebody cylinders and half dead solenoids cause most of the issues. Sent from my iPhone using Tapatalk

If the mileage is high it may be worth getting a Sonnax main pressure valve fitted. Worth doing a vacuum test first, but I find that I need to replace quite a few.

Wow, thanks Phil. That's a ton of information.
The X5 has 107k miles on it. It shifts perfect until it gets warm and then loses it's mind. Upper gears seem fine, so when I drive it (hardly never until this is fixed) I start in M-3 and drive easy until up to speed and shift into M4 & M5. Im not a transmission expert by any stretch, but appreciate the insight and knowledge you've shared. Here's the shop that's rebuilt a VB for me in the past. https://revmaxconverters.com/product...ed-valve-body/ A gentleman about 90 miles away will rebuild the transmission for $900 & a shop in Chicago is charging $250 to reman the L51. VB another $600. I'd considered a flush, but would rather just rebuild it instead of some now and some later. One shot and check all the boxes is what Im after. What fluid is recommended? Quote:

Only ever use either ZF Lifeguard Fluid 5, Pentosin ATF 1 or Mobil ATF LT71141 in your 5HP24. This guarantees that you have the right friction modifier pack to ensure that the torque converter lock-up clutch functions correctly in its ‘controlled slip’ mode

Had a similar issue, cant recall the codes, but the solution was simply replacing the harness in the transmission. Something about a thermostat/temp sensor that failed. Maybe you will get as lucky, but after a new filter, fluid, and the harness, all was great
