Everything was perfect before the "upgrade" lmao. So should I just order a rev max valve body or should I change solenoids again. Their was an issue with a weird sound on the 1 2 shift and dropped trans and brought to trans guy he said their was debris on solenoid. I wish he said change then if that was case but he took apart and checked everything. Sound did go away but after fluid change it does it within day or two again and only when warm
Try the revmax unit then. Let us know after a few weeks.

I knew you were gonna say that lmao. I just want make sure is it possible the unit could have been slightly worn and changing solenoids made worse ? I had no slips for anything and my adaptations are all good except a is showing positive values rest are negative. Just I been spending double on everything as usually with this car and I can get reimbursed for solenoids from fcp. Fml I'm gonna find out what a revmax costs. Do they do anything else besides solenoids and reaming for rebuild ?

Revmax has heavy duty solenoids...billet. sould be good with upgraded trans.

Now I just have to explain to my wife how I said wait until well pump dies instead of replacing and I'm redoing my tranny that she said leave alone cause its fine lmao. I hate when she is right

K and my upgraded bushings wont be affected right I know very little about our internals I know you have had yours apart and I am kinda like you where any slight issue will drive me nuts and I have to fix and if indont do the best possible I'll prob end up doing again lol.

Anyone with an old 'e' gen who continues to pour cash into it by now is not in his logical mind...he (WE) live in a completely emotional psychosis...logic and smarts has no place here.

By the power of Zeus, I will upgrade this car until it is impossible to do so any more technically. Then I will go onto the next journey.

Bushings are unaffected by solenoid upgrades... even if they are stock bushings. The ATF pressures are controlled by TCU calibration, the solenoids only open and close per TCU requests.

I have been and continue to drive with xHP testing all their options. So far, there are limited progress in each option. For example, when using the torque limiter on the "RWD" setting... I feel little difference to no setting. When using the 'reduce torque load engine request on shifting' option...also feel little difference. However, I do not get many opportunities to drive it full blast to see shifting behavior on any options of xHP. I will have to redo all options one by one and drive one week to adapt, then go on a full blast drive in normal mode, sport mode, and manual mode and write down notes of shift quality improvements if any.

Thought that was just me but options are dizzying and you have to save and back out menu each slider change or it doesn't always save all changes. It's very buggy on my note 9

You must always press 'save settings' before moving to another screen. Otherwise it won't save anything.

So did your prob come back after the upgraded ekp ? I know you said it is way better but you also said that still dont like stage 3 and not sure how you liked having the torque reduction way I recommended.

OK, here is the breakdown:

I. When I pushed the torque reduction upshift full to the left - -50%, the car was damn near uncontrollable. So I did -33, -33, -33,-40,-50 respectively. And I set torque reduction to 405,516, 700, 737, 737, 737. Now it shifts smoothly under normal driving and still not as ideal under high output. But better than before.

Now I do know what you are talking about when you say 1st to 2nd gear is clunky... mine is also clunky in that area too...however, it is ONLY when dragging in very slow traffic and 1st goes into 2nd gear...as in when I am stuck crawling in traffic...and doesn't matter if it is in sport or normal mode. So if this is what you are annoyed at, then I think it's a minor thing, because the car shifts perfectly when driving like a normal person... you cannot even tell it is shifting.

I believe that through constant adjustments and testing of settings, eventually we will arrive at the ideal settings for our PD unit. It is unfortunate that xHP are not interested in our situation. I also believe that replacing the VB with a RevMax will better the situation even more..although it may not make it perfect, still it would most likely be better than the VB we have currently.

This is because Revmax supposedly uses computer controlled bore machines that are superior to hand bores when they do their reaming process. And I do not believe that the German asshat in Georgia has that machine to do that...they have a dyno for transmission...but they do not have the machines that Revmax has because Revmax specializes in VB and is a bigger company than the small Georgia Eurotrans shop that does everything. The bore machine alone costs a shitload of money and I don't think a small shop like the German guy has the funds or business to invest in such a machine just for valve bodies.

As a result, I believe that I have an inferiorly remanufactured valve body that is a big part of the shifting problems we are both experiencing. This is mainly due to not only the above conjecture, but also personal witness of the valve body state and parts during my sonax zip kit overhaul. Nothing I saw in the valve body was upgraded, it was all stock and nothing extraordinary. By contrast, I have had a RevMax valve body before and I can tell you that their solenoids are indeed insanely built with star trek looking billet parts. And I have no reason to doubt that all their internal pistons and bores have been computer rebored and pistons replaced with pristine new ones.

So it appears that you will be the first one to see the benefits if you install a RevMax unit. I cannot do so at this point because of budget, but rest assured, I will when finances are in order.

What kills me is how can xhp stage 3 be calibrated for pd and for stock trans at same time. Anyway I have to get the number off casting for ordering rev max valve body so I ordered new solenoids and mechatronics sleeves again since i can get refund from fcp so I am giving it shot and then will order the rev max if that doesnt work.
