Auto tranny, worth any mods?

ggcadc · 04-23-2013, 01:20 PM

I got an auto for my own reasons (my wife says I can build a racecar once we get a garage if I have a regular DD fro a while).

so the question is, are there any mods for sulev auto worth doing? Ive already got H&R sways going in this week... im not sure if there are any other mods that may make me happier with the overall performance, I think the sways wil balance the chassis a bit more, i got DEPOs, they look better with the blacked out grills. Im considering the camber adjustment up front with the DIY to remove the pins. Other than that im thinking it might be a waste to dig into engine mods considering the GM6auto is in the way... but it is comfy as a DD.

ggcadc · 04-23-2013, 10:59 PM

I will take that as a decided no

Good choice on the sways

Look into
bmw perf suspention or eibach kit
AA tune - people with autos say good things about the tune
Air box/air intake- at the minimum a charcoal filter delete

Most people with auto's don't tend to be into modding. with that said, my friend has an auto 2011 and she's been modding hers slowly but surely. I assume the auto tranny can hold power from headers/disa manifold/tune, but again i'm not quite sure if it's ever been done.

Regardless of that, feel free to mod to your hearts content. I drove her car and while I'm not a fan of letting it shift for me, the handling is the same and can be truly appreciated in auto and a 6MT.

You can check my sig for the mods I've done to my auto. I think the power box works well with the auto cause it seems to hold the gear longer rather than up shift at 1500 rpm in daily driving. I would do everything over again. I love the way it handles.

i have auto tranny

i don't think there are specific auto tranny mods except for BMS power box that will make the pedals less laggy

This might actually be what you're looking for. I've never tried it but a lot of e9x auto guys seem to swear by them.. usually about the improved DS mode.

At sub $300 it might be all you need to get a little extra pep in your step. Get it?! Pep..in.. step.. Tronic!!. Caus..ahhh'll see myself out now.

ggcadc · 04-25-2013, 01:18 AM

alright, i dig the BMS idea, if it remaps the sport trans mode that is worth a look

alvitdk · 04-25-2013, 07:31 AM

I got the AA tune, and what a difference it made, not just throttle responds but in the power delivery between 2k and 4k, I think it adds abut 10-15hp. I also used the auto to 100% as a manual, once you get used to it, the only thing missing is the 3rd pedal, upshifting is fairly quick, compared to other automatics.

I also added a different shifter knop, the illuminated Bimmian, adds new modern BMW look to the car. (did I mention I have mine for sale, as I sold the car ;-) )

Anyway, I can only recommend getting the AA tune, well worth it.

What is the max hp/tq rating for the GM6?

ggcadc · 05-04-2013, 09:09 PM

im fairly sure no one knows

zoomnad · 05-05-2013, 06:19 AM

Having had a manual trans all my life, things change. After haveing surgery on my left knee, I now have a auto. I love manual but the auto doesn't change my mind about modding, how I drive (fast) or love of cars. Now if I only can stop slaping my shifter in neutral and stop pushing the non-clutch pedal.................

The auto transmission is the same as the one used in the ATS turbo, which has a much higher torque rating than the N52. It is rated at 332 ft-lbs.

don't mind me, just making my 1st post to make 1st thread. My apologies for the off topic post

Question on your swaybar choices " E93 FSB, E92 RSB," why the vert front and coupe rear? I ask cause I’m looking at the Eibach kit and it’s a 28mm front (~ M3/1M) and 15mm rear (~ E93). Also I didn’t notice a LSD and I’m wondering if I really need one considering the setup you have (and I’m considering); would really appreciate your thoughts.

After exhaustive searching on here, I decided to go with the thinner bar for the rear. Without an LSD on hard cornering, you can lose traction on the inside wheel from the thicker bar because it lifts the more of the load off of it. I don't think it is as severe on the 128i as it is on the 135i, we just don't have as much torque to really break the rear loose like you can on one of them. Especially if they are tuned. At the time I figured I would get an LSD in the near future. I tried to find an LSD that would work with the auto 128i but couldn't find one. It seems that the manual 128i does work with some of the LSD's out there. If you find one let me know.

How much did this cost you? I'm looking into doing this to my auto!

Badabing · 06-30-2013, 12:16 PM

I too am looking at this. The aa tune seems like it might be the best option for us autos.

bozola · 06-30-2013, 12:32 PM

Performance exhaust is a good choice. Not much so for the 3 hp, but for the sweet intoxicating sound.....
