2 1/2 qts came out and i just refilled it back with new tranny oil.

Oh well, tranny blew up because of something but i'll have to check tomorrow to see what happened.









j/k :) it felt like it did shift faster going full throttle compared to before but i'll have to see when i race my bud's M3 again. when we raced he would gain on me everytime i shifted gears, due to the slow shifts. Seems like the shifts are also smoother like it didnt shift gears at all. pretty cool i say.

Oh btw remember to unplug your battery before you do this as i got a CEL after this and had to reset it cause i forgot to do it

Nice man! Do me a favor, definitely keep us posted on how the car feels because it could be:

- smoother, perhaps quicker shifting due to replacing the fluid with new
- you just re-set your computer; whenever I re-set my computer it always seems to be running better for the first 5 miles or so.

I just want to see if these are REAL results and not from anything else. Perhaps 1 FULL WEEK of driving will tell the truth. Please report back and thanks for doing this!

Did it this afternoon.
It does not matter how many times you rotate the valve 360 degrees, it is a floating valve. The difference in line pressure is accomplished because the three "indentations" are of different thicknesses. Depending on which "cutout" the key sits in determines the line pressure.

It definitely made a difference in shift speed and firmness. No where near a shift kit and not objectionable at all. I am getting a slight 1-2 shift flare at part throttle sometimes now though, I'll wait to see if it works itself out or dig in to see if I can find the problem.

I did not disconnect the battery nor did I get a CEL.

Cool, I bet the valve can be modified. I guess, based on the pic, the softer the shift, the more the valve extends out. I woundn't modify it...unless someone dares to pull the valve out :) or find pics of that valve. If someone wants to put a v plate to have that extra ooomp, that'll be interesting (the other hand, it could mean destroying the tranny). Wondering if it really does what OP says it does.

Good Info.

does the gs300 tranny that jeff has, have this same valve? i would assume so but i havent ever paid attention to the I-6 or its tranny

DeanGS 10-11-11 10:32 PM

All A650s in the GS line are the same internally. Only difference between the GS3 and GS4 is the torque converter and bell housing.

According to wikipedia The IS300, GS300, GS400, GS430, LS400, LS430 got the same transmission. :thumbup:

any updates?

DeanGS 10-16-11 09:28 PM

No problems, the1-2 shift flare went away the next day. Shifts are still firmer.

erikbang 10-22-11 11:45 AM

Very good mod...did it the other day. Shifts are crisp and firm. It's very similar to a mild shift kit. :thumbup:

How many times did you turned yours clock wise?

erikbang 10-23-11 12:32 AM

It was 3 clicks clockwise. Tab will fall down if you let it, so be careful. This is not 3 full rotations.

cdg306 10-23-11 06:41 AM

Anyone else try it? Curious about any long term effects.
