lieutenantcolumbo Posted May 11, 2012 Share Posted May 11, 2012 But was that from wot in 5th or wot shifting to 5th? Driving in normal auto mode on highway, was in 5th. Would have to be going pretty fast at for a WOT shift from 4th to 5th in normal auto mode. I was looking for more of an explanation, not just a short response I sure CD could answer the technical part better, but I believe 4th & 5th have fewer clutches and share an input shaft. I had to have my case machined so they could add extra 4th & 5th gear clutches. Link to comment Share on other sites More sharing options...
Mega Users LieutenantDan Posted May 11, 2012 Mega Users Share Posted May 11, 2012 I'm having a used 5eat installed to replace mine that is breaking. I'll be getting your valve body upgrade when I return from my summer internship. The shop doing the install recommended I replace the Axle Seals, the pump seal, and a new filter kit. I know the Axle Seal is straight forward but not sure about the pump seal and filter kit. Does the filter kit entail screens and filters inside the tranny? Also not sure where the pump is. So, for the FAQ...what should I do to properly prep a used 5eat to increase its longevity? Link to comment Share on other sites More sharing options...
JonnyWachter Posted May 12, 2012 Share Posted May 12, 2012 Will the shifting be firmer and have better response with the valve body upgrade? Link to comment Share on other sites More sharing options...
OptimumLGT Posted May 12, 2012 Share Posted May 12, 2012 Does the valve body mod for the 07's kill the autoshift at the redline? Link to comment Share on other sites More sharing options...
LGTDuncan Posted May 12, 2012 Share Posted May 12, 2012 Where are you at in the process of upgrading the clutch packs for the 5eat, specifically for a 05-06? And what do you think the power limits will end up being? I love having a automatic for an everyday driver and would like to be able to have a 500hp legacy wagon 5eat sleeper!!!!!

Rome_STI Posted May 15, 2012 Share Posted May 15, 2012 Why does my car hold 1st gear on occassion when I WOT from a standing start in auto mode? It will rev to redline, hit it once or twice, then shift into second. It doesn't do it all the time, only sometimes, and it almost never does it if I WOT from a standing start in manual mode Why does my car shift itself before I can when WOT in manual mode. It will also register my shift so what ends up happening is it revs to redline, shifts itself, then because I had already shifted it up, it goes into 3rd almost a second later Link to comment Share on other sites More sharing options...
fishbone Posted May 15, 2012 Share Posted May 15, 2012 That's a combination of shitty shifting logic and not being able to shift fast enough (when you end up hitting redline in 1st). It's not uncommon for modded autos to do that sort of thing. Mine does it too once or twice every year. If it happens, it happens if I haven't floored it in a very very long time.

Alfred_Buchi Posted May 22, 2012 Share Posted May 22, 2012 Is downshifting a 5EAT hard as bad as upshifting? Link to comment Share on other sites More sharing options...
bmx045 Posted May 22, 2012 Share Posted May 22, 2012 I hear that subaru recommends pressing the accelerator a little while manual downshifting to speed up the shift, like rev matching. The more you can equalize the engine speed with the speed of the car in the gear you want to go into will make a smooth downshift. Some downshifts are hard even in a healthy 5eat Link to comment Share on other sites More sharing options...
OptimumLGT Posted May 25, 2012 Share Posted May 25, 2012 ^^ that sounds kind of dangerous... Is it bad to use your transmission to assist with braking? I was under the impression that the ECU has to many fail safes for you to over rev on a down or up shift. Link to comment Share on other sites More sharing options...
bmx045 Posted May 25, 2012 Share Posted May 25, 2012 (edited) no it's not dangerous equalizing engine speed(at very small, to no loads) to car speed while shifting results in the least amount of friction. engine braking is fine(also called dynamic braking). and ecu and tcu will not allow you to overrev or switch to a lower gear causing overrev.

Mega Users seabass07 Posted May 25, 2012 Mega Users Share Posted May 25, 2012 You won't really over rev on a downshift since the tcu won't let you. You can downshift and end up at redline though bouncing off the limiter. I've done that a couple times from just pressing the wrong button by accident. Engine braking isn't bad. I think you'd have to be towing to over do it. Link to comment Share on other sites More sharing options...
bmx045 Posted May 25, 2012 Share Posted May 25, 2012 And i dont mean slam the accel pedal down. Just gently to bring the rpms up to match the gear below. Its what the term rev matching means Link to comment Share on other sites More sharing options...
fishbone Posted May 25, 2012 Share Posted May 25, 2012 People, people, people! It's an auto ffs, you have 2 jobs: hit the gas or hit the brake, depending on need. Anything above and beyond that, if you want to dick around, get a MT 07-09 will revmatch on downshifts, 05-06 I have yet to hear of a failed transmission because it didn't like to be downshifted.

If you kee an eye on the gear indicator and rome when going wot 1st gear in manual mode, the indicator jumps to 2 at a MUCH lower rpm then redline. I'm talking just under 5k sometimes. Drives me nuts. Not ideal but I usually just let it shift itself out of first. 09 valve body + the manual mode shift interface being tighter, I wouldnt be jealous of an MT.

bmx045 Posted May 25, 2012 Share Posted May 25, 2012 when in manual mode and S# for 08+, it will shift at redline. if the gear indicator changes gears it doesnt mean its now in that gear. it's probably to inform you when the tcu prepares for the upoming shift. atleast in mine, i have an mt map flashed on my car.

ktm200 Posted May 25, 2012 Share Posted May 25, 2012 I know it doesn't actually shift. But when the indicator jumps to 2, and the tranny is still in 1, if you pull the paddle to upshift, the car then jumps to 3rd immediately Link to comment Share on other sites More sharing options...
bmx045 Posted May 25, 2012 Share Posted May 25, 2012 yeah that is annoying. i learned to just let it do its thing, and know ill need to press the paddle sooner to not trip the computer Link to comment Share on other sites More sharing options...
Medicinebow Posted May 26, 2012 Share Posted May 26, 2012 So to clarify... General consensus is engine braking isn't hard on the 5EAT? I really only do it because I love the sound of my exhaust. Link to comment Share on other sites More sharing options...

planelazy Posted June 3, 2012 Share Posted June 3, 2012 So to clarify... General consensus is engine braking isn't hard on the 5EAT? I really only do it because I love the sound of my exhaust. Like SeaBass said, it doesn't damage it. I do it all the time... probably pisses people off since I slow down with using the brakes.. thus no brake lights And the TCU won't let you shift if it's going to do damage to the engine (as far as going past the redline). In our 5eats, the tranny should go before the engine. Link to comment Share on other sites More sharing options...
