so is it two clicks clockwise or three? One did three clicks, the OP did two? Which one is it to be safe?

Lexus doesnt have one for sale because they dont use one since they use a gasket maker. some red ATV paste. works wonders but its a PITA to clean.

Just caught this thread and I just so happened to be changing out my tranny filter today.

When I dropped the pan to look for this dial, low and behold the adjustment had already been made ! ! !

So apparently RMM has known about this adjustment and I suspect it was part of the process when the new valve body was installed.

You can take my assumptions for what it's worth but the REAL point here is that I have been running with this modification for over TEN YEARS of which my car has been supercharged for 5+ of those years.

It goes without saying that I have driven my car hard on occasion and I can tell you the tranny has functioned without any reliability issues thoughout these 10+ years. Also note that I have a hi stall TC and I'm running AMSoil synthetic.

Based on my findings, I'd say this mod is good to go.

What's the part number of the tranny filter? I am looking to do this mod and want to change the filter too while I'm in there.

Thanks

Many thanks.

Looks like it should be the same on all 2GS trannies, but I'll double-check.

Dont you think they would have told you about the "mod"? Why wouldn't they want you to know they did something beneficial?

EIther way I'd say thats a good thing

They probably wanted it to be their secret to go with the valvebody mod....no reason to give away their trade secrets.

Meh, agreed... but even that is silly. Its leading you to believe that the extra performance is placed solely on their products.

Since you and many others are new to the forums, the OGs know the history of my car is that I bought it from Rhys Millen with all their mods already installed as this was their original RMM car, hence my screen name.

The valvebody mod itself is "legit". This pressure adjustment is not going to make or break the performance, it's just a tweek. On the other hand, this mod may be only something they did as an additional tweek for "themselves". Since they no longer offer the valve body mod on their site, there's no telling whether the instructions would of included this adjustment, but all this speculation is neither here nor there.

http://rhys-millen-racing.myshopify....s-transmission

The only real point of the information I provided is establishing that this little mod has been tried and proven reliable for 10+ years on my car.
