godwhomismike Posted September 15, 2007 Share Posted September 15, 2007 New Thread - discuss the differences between the 1st and 2nd generation 5EAT transmissions here. I'm assuming that's the 1st generation 5EAT. Apparently, the new one is completely revised and has a brand new torque converter. . Link to comment Share on other sites More sharing options...
Richard B. Posted September 16, 2007 Share Posted September 16, 2007 The 335I uses the Steptronic gearbox which is a great fast shifting auto gearbox. The SMG is not used on the 335I's. On that note Subaru needs to introduce a DSG type gearbox. yeah. i think i read somewhere something about 100ms shifts. according to subaru the new 5eat is either .2 or .3 seconds. pretty quick overall i say.

This is true, and I am dying to test drive an 08 LGT w/ 5EAT to verify if it is indeed quicker. / Link to comment Share on other sites More sharing options...
Carter Posted September 17, 2007 Share Posted September 17, 2007 I have an 08 LGT with a 5EAT. Is the shift quicker? Yes and No. I would say the acutal shift from gear to gear is quick, but the "command" to change/shift gears is slow. Using the auto mode and letting it do its thing accerlating from a stop is fine, but if youre up to speed, and press the accelerator to down shift to pass someone, the shift seems to take a while. Same goes for the sport shift mode for manually shifting. When I accelerate in sport shift, and use the paddles or stick, I have to up shift early. It seems like the RPM's will rise by 1500 or so before the transmission will actually shift gears. Link to comment Share on other sites More sharing options...

There was a delay in the upshifting and there were a few times I bounced off the limited because of this. I wonder if it is a little quicker than the '05, or did all the new electronics slow it down a little. . Link to comment Share on other sites More sharing options...
Carter Posted September 17, 2007 Share Posted September 17, 2007 I have never driven a pre 08 LGT so I dont know how quicker it is... Link to comment Share on other sites More sharing options...
godwhomismike Posted September 17, 2007 Author Share Posted September 17, 2007 I have never driven a pre 08 LGT so I dont know how quicker it is... How's it feel now that the temps are in the 50s or lower? Does it feel quick, or do you have any mods? . Link to comment Share on other sites More sharing options...
Richard B. Posted September 17, 2007 Share Posted September 17, 2007 This is true to certain extend. The dyno has also shown that 5EAT puts down less power than the 5MT. it's has even been posted by a tuner that due to gear ratio differences you can not directly compare them. think about it. shorten the ratio on any sti 3rd gear and tell me if you will get more/less power just from doing that.

Richard B. Posted September 17, 2007 Share Posted September 17, 2007 This is true, and I am dying to test drive an 08 LGT w/ 5EAT to verify if it is indeed quicker. / it wont matter. they regeard the final drive to make it slower. quicker shiting with a slower ratio. funny though. the 3.0r got the quicker tranny gearing. other wise it woul dbe even slower than it is now. unfair to the gt owners imo. also, imo, it's another way that subaru says f**k you to the years previous customers. seems like they have the start of a fine package but then go out of their way to f**k it up severely. WHY!!!!??? Link to comment Share on other sites More sharing options...
godwhomismike Posted September 20, 2007 Author Share Posted September 20, 2007 so how much of a loss are we talking with the new second generation 5EAT? Is small enough, where an intake & exhaust would compensate for the slower gearing? . Link to comment Share on other sites More sharing options...
godwhomismike Posted September 21, 2007 Author Share Posted September 21, 2007 Ok to catch up here and put this thread into perspective. According to Richard B, he claims that the 5EAT is revised completely on the 2008 models so that the gears are set to slow up the 5EAT on the GT, where the gearing on the 3.0R is changed in a way to make it quicker. What are the gear ratios of the 05-07 5EAT vs the 08 5EAT (GT vs 3.0R) . Link to comment Share on other sites More sharing options...

BUT...the new tranny supposedly shifts much quicker. so that alone may make up for it. i dunno. AND if subaru dropped in a better turbo...just speculating now.

AKLGT Posted September 24, 2007 Share Posted September 24, 2007 i just need to go and test drive the new 08 and see if there is that much of a difference in the 5EAT. Wiggle wiggle wiggle wiggle wiggle yeah!!! Link to comment Share on other sites More sharing options...

Knight705 Posted September 26, 2007 Share Posted September 26, 2007 wouldn't the lower final gear means that the 08 lgt can hit higher top speed? if the limiter was removed? Link to comment Share on other sites More sharing options...
chenc544 Posted September 27, 2007 Share Posted September 27, 2007 wouldn't the lower final gear means that the 08 lgt can hit higher top speed? if the limiter was removed? Theoretically, but I don't believe the stock LGT has enough power to reach the limit of the gearing. IIRC the the '05-'07 gearing tops out at ~180+ mph, '08 would be about 5% higher.

AKLGT Posted September 27, 2007 Share Posted September 27, 2007 well, they are out of 08 5EAT LGTs so i have to wait. but i did test drive the new 08 WRX hatch. nice... reminds me of when my LGT was stock.

SWP-LegacyGT Posted September 30, 2007 Share Posted September 30, 2007 I've driven the '08 5EAT. The shifts are smoother, but I wouldn't say any faster. Also it was a different story driving a stock '08 5EAT and my Stage 1 5EAT. The rev matching is really the only thing that works better with the torque converter. Until a '08 5EAT is dyno'ed, we really won't know. Link to comment Share on other sites More sharing options...

Richard B. Posted October 7, 2007 Share Posted October 7, 2007 It still has the 4EAT. . i hope it stays that way. we pay a little bit more than the wrx peoples and i find the 5eat is at least 1 reason why. when the wrx gets a 5eat i want the b11 6eat for a gt. well...maybe a sequential instead.
