Mega Users seabass07 Posted April 25, 2014 Mega Users Share Posted April 25, 2014 Nope. 3rd. That's the odd tcc behavior. Id have to give it a significant amount of gas to get up the hill and that would disengage the tcc. It wouldn't lock up at all while going up mountain passes unless I started going up above 50mph. If I started out slower, it would hang up at the stall speed and sit there heating up the fluid. Link to comment Share on other sites More sharing options...
eric_t Posted April 25, 2014 Share Posted April 25, 2014 Engine temp never went higher than normal. I stopped often enough for fuel that I could feel out the car in acceleration and deceleration, gear change harshness, etc.. fluid looked exactly the same after the trip as before the trip. (overheating would have caused the fluid to "burn" and discolor) I drove I-80 across. Towing has a LOT to do with the driver.. I knew i'd be okay towing, guess I just freaked out since i'd never towed with a CAR before. It's still almost a brand new car, I mean 20k miles on a 2009 3.0R.

Mega Users seabass07 Posted April 25, 2014 Mega Users Share Posted April 25, 2014 Ahhhh. That explains everything. You have an h6 which has a different torque converter. Completely different since its not a high stall. Link to comment Share on other sites More sharing options...
eric_t Posted April 25, 2014 Share Posted April 25, 2014 yeah...thought i made that point before (when i asked questions before towing). the car did better towing that than my f150 5.0 with a 7000lb boat trailer. got better gas mileage doing it, too. lol Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted April 25, 2014 Author Share Posted April 25, 2014 Specifically, 2009 non-turbo stalls 1900-2300 rpm, where turbo stalls 2300-3200. That is a massive difference.

fishbone Posted April 25, 2014 Share Posted April 25, 2014 (edited) Unless you're an asshole. Then it's close to 4K rpm. The repair manual says at sea level, stall speed for turbo is 3100-3500, non-turbo is 2400-2800. The outlined procedure to test the stall speed is: -bring the car up to normal operating temp -mash your foot on the brake pedal firmly -put the car in 2nd gear -press the gas pedal gradually and take notice when the rpms stabilize, stop accelerating -don't do it for more than 5 seconds counting from when you touch the gas pedal until you've gone WOT The manual says if you do it for too long you can damage the ATF and the clutch. It doesn't say which clutch. David? Edited April 25, 2014 by fishbone Link to comment Share on other sites More sharing options...
fishbone Posted April 25, 2014 Share Posted April 25, 2014 Nevermind, I think I got my answer. You can follow the same procedure with the car in Reverse too. Link to comment Share on other sites More sharing options...

That is a massive difference. Only because the turbo motor makes more torque at the lower rpm! It's probably the same torque converter Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
frank_ster Posted April 26, 2014 Share Posted April 26, 2014 Stall test should not harm any clutch. It's bad for the torque converter. Â On my sunbird I bent all the vanes inside. It was about 5000 rpm stall at the end and worked great !

fishbone Posted April 26, 2014 Share Posted April 26, 2014 I ask because I've sat on the brakes at the dragstrip for longer than 5 seconds. I imagine other than stressing the ATF, as long as the rpms did not exceed stall speed, no harm was done. Please say I'm right. Link to comment Share on other sites More sharing options...
frank_ster Posted April 26, 2014 Share Posted April 26, 2014 Lol I have done way worse than you ! I built boost until the ecu got power down signal from the tcu. Â Brake boosting or even trans brake are commonly used . And I haven't really herd of any specific issues to the 5 eat converter. If there was I'd surly be having them !

frank_ster Posted April 26, 2014 Share Posted April 26, 2014 Nope it's why the gt is faster than the h6. The gt actually has more low end and mid range torque . The gt has lag but once the turbo catches up it has more power everywhere Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
underpowerd Posted April 26, 2014 Share Posted April 26, 2014 One for the top brass: What is the task of the lone exposed diode on the VB unit (capacitor, fuse, switching, volt. reg, etc.), and what symptom(s) would one expect to encounter if fully/partially burned? TIA, gents. can anybody field this one (mr. dave/frank ?)? can snap a pic if description unclear... Link to comment Share on other sites More sharing options...
frank_ster Posted April 27, 2014 Share Posted April 27, 2014 not sure what your asking about can you take a picture? just from what your explaining it might be the pan oil temp sensor Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
underpowerd Posted April 27, 2014 Share Posted April 27, 2014 (edited) thanks frank -- bah, i didn't even think of temp sens. you're probably right -- i was hoping like hell for a fuse/capacitor. pics attached; i was referring to the red guy in the center. here's the thing: i had a fluke short of two wires (YR, Blk) of the giant harness (B21?) care of the turbo oil feed. when the two ultimately wore through enough to short, it was taking F/B#12 out instantly @ 'on' key turn iirc -- being a 20* evening, it activated my AAA card, lol. so as i see it, the #12 fuse did its job with the direct short, but it appeared that the YR wire had been exposed far longer than the black, and as i understand the pinouts this wire is a very heavy fellow with regards to the 5eat and may have seen some intermittent (-) contact, again via the oil feed which i imagine must carry some ground.  i may be jumping to conclusions, but my mind can't help but to tie my long-standing P0700/740 (tcc sol) to this unfortunate sneaky situation; i just think that if it were something more mechanical like worn clutches (as some others have reported with this code), i'd have certainly seen a failure by now. i have no slipping whatsoever, and i get the sport flash on proper cue (in M2+ on slight incline @ 1/8 throttle or so [mostly M3+]) to suggest procedural vb replacement.

Vaders_3.0R Posted April 28, 2014 Share Posted April 28, 2014 Is it normal for the trans to aggressively (not harshly) downshift upon hard braking? (Drive in S#) I have the rallitek trans mount bushing installed if that makes a difference. Trans and drivetrain were serviced like 5k ago.

Mega Users seabass07 Posted April 28, 2014 Mega Users Share Posted April 28, 2014 The 05-06's do that in sport mode. I think they kept that logic in the 07+. Link to comment Share on other sites More sharing options...

fishbone Posted April 28, 2014 Share Posted April 28, 2014 Anyone else having the lazy 1-2 shift? Most annoying issue about the trans. It's the one behavior that's keeping me paranoid about slipping clutches. Link to comment Share on other sites More sharing options...

JMLegacy Posted April 29, 2014 Share Posted April 29, 2014 Do u have a lazy third gear during lockup? What causes this? https://www.youtube.com/watch?v=9RHqAtZuM5Q check my video out for reference. When it reaches third, it slows right down. It even shows on the road dyno a huge dip in the lockup region. I get higher numbers in 2nd gear Link to comment Share on other sites More sharing options...
frank_ster Posted April 29, 2014 Share Posted April 29, 2014 looks fine to me .. if the tcu could me hacked that be made to engage harder. Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
fishbone Posted April 29, 2014 Share Posted April 29, 2014 The 1-2 lazy shift, as far as I can tell, is there on purpose to smooth out the operation of the 5EAT and ensure a comfy ride. As a result, it may sometimes lead an overly cautious and OCD performance oriented enthusiast owner to question whether or not the clutches are slipping. That is the ONE thing that my IPT valve body did not do a whole lot about. It is a learned behavior by the TCU. I know this because upon TCU reset, it shifts kick-ass. It also shifts kick-ass after a short stint of driving like a jackass. Then the trans firms up. Basically I need to stop driving like an old person 90% of the time.
