fishbone Posted May 17, 2016 Share Posted May 17, 2016 ben64, it depends how it is done. If the fluid is drained and refilled then no, the fluid that is in the torque converter is trapped there and is not exchanged. The only way to exchange all the fluid at the same time is to use a fluid exchange machine. The control valve body is the brain of the transmission that makes it go vroom-vroom and shift gears.

KGB Posted May 17, 2016 Share Posted May 17, 2016 How much torque do you expect from this turbo? With a HexMods VB you should be okay to 400wtq, maybe more... Do it Before the turbo or bravely risk watching the Tranny grenade on the dyno So my 20g twinscroll met an untimely death when the clamp bolt broke and bent a few turbine fins. So rather than fix it it's being upgraded. New turbo will be a 60-1 twinscroll with 9 blade turbine. Car will be tuned on 91oct. Countdown to transmission/rear diff explosion?

utc_pyro Posted May 17, 2016 Share Posted May 17, 2016 So my center diff took a dump a year and a half ago requiring a new transmission. Local deanship refused to install the new one due to the debris floating around after this. I want to install my Transgo valve body in the new transmission. Are there any filters or anything I need to clean/replace? Is it probably good to go as is? Should I just have them rebuild the new valve body with the springs/valves from the old one?

quick4dr Posted May 18, 2016 Share Posted May 18, 2016 popped radiator on my 5eat. ordered new aluminum Koyo unit. I run my trans with external cooler with derale plumbed in the climber D preferred routing. any ill affects from not having a cooler built into radiator, and just having the external unit?

snow05gtRI Posted May 18, 2016 Share Posted May 18, 2016 friendly reminder to check your trans fluid level. Mine was about half way between the cold low/full and hot low/full marks. Put enough fluid in to bring it up to the hot low/full marks and it's feeling much smoother. Link to comment Share on other sites More sharing options...
MTBwrench Posted May 18, 2016 Share Posted May 18, 2016 popped radiator on my 5eat. ordered new aluminum Koyo unit. I run my trans with external cooler with derale plumbed in the climber D preferred routing. any ill affects from not having a cooler built into radiator, and just having the external unit? Technically, yes. 1) in cold climates you don't have coolant to heat the trans up quicker. 2) the external can cook the trans too much, but thermostat should help. Just watch your trans temps and make sure it stays safe. MTBwrench's Stage 3 5EAT #racewagon 266awhp/255awtq @17.5psi, Tuned By Graham of Boosted Performance Everyone knows what I taste like.

abaig97 Posted May 21, 2016 Share Posted May 21, 2016 whats the most power anyone has gotten out of a 08 5eat, since it doesnt have any valve body upgrades Link to comment Share on other sites More sharing options...
Mega Users seabass07 Posted May 21, 2016 Mega Users Share Posted May 21, 2016 It can fail at stage 2. Link to comment Share on other sites More sharing options...

snow05gtRI Posted May 23, 2016 Share Posted May 23, 2016 What AT fluid do you all recommend? Subaru ATF-HP (make sure it's the -HP version for the turbo 5EAT) works just fine. Some others like Amsoil but I don't know which specific flavor Link to comment Share on other sites More sharing options...

Why would anyone want to beat on a car after modifying it? Just stick with the weak link trans and baby the car after adding a significant amount of power. Makes sense.

RooTBeeR Posted May 24, 2016 Share Posted May 24, 2016 Heats not really the issue at That point. Line pressure on the clutch pack wont hold the torque.

fahr_side Posted May 27, 2016 Share Posted May 27, 2016 Heats not really the issue at That point. Line pressure on the clutch pack wont hold the torque. But you can increase line pressure by tuning Requested Torque and Calculated Torque tables in the ECU. Like this we are pushing 50kgm / 408whp through the trans in the BR9.

Mega Users seabass07 Posted May 27, 2016 Mega Users Share Posted May 27, 2016 So something actually came of that? Last I checked, it was inconclusive. I know it didn't seem to have a significant effect on the 05 5eat. There was a slightly noticeable change in shift hardness, but nothing like you get from a modified vb.

whitrzac Posted May 28, 2016 Share Posted May 28, 2016 The requested torque table was the one to change on the 05-07 ecu. IDK if it does anything. The target boost table makes a BIG difference in how the trans shifts. I've been tempted to set it to all 99.9 just to see what the car does.

Higher RT values both raise the shift rpm points and increase line pressure, though the former is more obvious than the latter IME. Sent from a device using some software.
