I had a Valve body rebuild kit installed and it really mad a difference, as the flushing is just a band aid. I'm also in the process of trying to find a way to build the TF80 without going through Level 10, which has not had a lot of positive reviews. I have been on the phone with all of the above sources for the valve body. It seams there are really only three manufactures of the parts in the USA. Will update here when we find out how well it holds up with the new higher HP motor going in.

Would like to here if anyone has done any upgrades to this transmission, as most of the cars this transmission cam in are not most built, think Ford Fusion, and 500

Did you get that transgo kit installed? If I remember right it was only around $100ish. It take that over an iffy rebuilt

I had ARD do it last year, They used the AW factory rebuild and this is what they did

Shift solenoid kit. Includes SLT, TCC, B1, C1, C2, C3 1 ( PArts wich were just under $600.00)
Install shift solenoid kit 4.20 hours Labor

Before the upgrade I was able to brake boost to about 4K then go, After I can only get it to 2500 rpm and it will hold it there. This was one of the best upgrades I have done to the car. I will post what we find in the hopes of saving people some money. I can say STAY away from the Level 10 ECu flash. A total waste of 200.00 . When I called them today I got no details just 'Sure our transmission will hold 500 awhp "

Yeah, I'm definitely not trying to disprove your theory. If anything, I'm trying to prove your theory...or any theory. I just want to know the answer. LOL

I suspect what you've presented is accurate. My real goal is to just keep collecting and collecting data points until we finally prove out the answer.

My other goal is to (finally) bring this issue and its overwhelming reach to light. Years ago I thought this was just a few early R's and that I got unlucky. I also previously believed this was just an issue that could "possibly" affect a vehicle before 06J. Years later (and MANY threads read) I've realized this issue affected every unit within multiple model lines for multiple years. There's a lot of vehicles that will, at some point in their life, be affected by this. There's a reason several shops have set themselves up to rebuild and update these units. They've realized the scope and now, we finally are realizing it as well.

Thanks again to all who have submitted data points and KEEP THEM COMING!

I would be very interested to know the shops that update these. Been looking for a specialty custom shop.

I agree with you. A TCM tune is desperately needed.

You are correct Neal, as it is a software issue beyond adjustments to the valve body. See if you can get braised fin's for your torque converter. My car does have adjustments in the software for faster shifts in works. Not cheep but should be worth it with the paddles

The speed at which the display changes isn't directly connected to the control logic of the transmission. It immediately acknowledges you've requested a gear change, yes. But the cycle of changing gears is a several step process: TC unlock, feather TC pressure to "release" input torque, change gear, ramp TC pressure to engage input torque, lockup TC once input/output shaft rpm syncs. The solenoids that operate all of these steps (except TC pressure control) are open/closed style valves and that happens extremely fast.

I'll wager the mechanical changes you made to the valves had larger orofices, yes? If so, this just changes the rate at which the gears and TC lockup engage, this makes it feel "firmer" but doesn't change the speed at which the commands are given.

Some of the steps will happen faster but I think the overall process will still feel slow. Please update us once you've got it running, i'd like to know how much of a difference it makes.

The shop that rebuilt my transmission believes in smooth shifts rather than hard pounding shifts, which he believes will handle more power and be more reliable

Ron you've been saying your trans is in the works for the past 6 months and you never share any info of what it is you're doing to it to help other members out.

How do you know what they're doing to the trans actually works?

¯\_(ツ)_/¯

Well, I'm old school. I have a full schedule currently with a new BIZ. I did take the time to research ideas for my team and handed that information to them. I don't have the time or space to do any automotive work anymore, as much as I miss it. I do like my R and my XCR DD ( Stage II 2000 Xc and 98 Stage II V70T5). So what you will get from me is what CAN be done. I take the time to find those shops who are custom builders. They don't give their work away and I will give their name to those who want use their work, and not just call them and ask how they did it. I give a lot of ideas of what CAN be done. Those with more time can research and figure out the details. I'm sure when other tuners figure out the DEM mod they will not just post the code( Now you know it can be done). I hope you can respect the time that those who did my transmission put into to finding ways to make it work. Also this build will take as long as it takes. Sure it's been 18 months but you were not around for BoostedR's over 2 1/2 year build. The ability to dedicate whatever time it takes is what I have now at my age, that I never had before. To me the car just left a month ago as busy as my life is. Read between the lines and get creative. My build team gets put down, but they keep me happy. I look forward to others coming up with new innovations that I look forward to PURCHASING to reward their hard work. The car will be back at some point and back on my home town Mustang Dyno. It will also be at a half mile race to see if the work has paid off. If it breaks it's back to the shop to fix and make it better. The goal of CKA Motorsports, is to see how far I push this car, for half miles and mile racing
