    • Level 10 Performance Transmissions Building the First High Torque Capacity Automatic/Steptronic Transmission for the N54 (335/135/535)

      As many, probably all of you know, I've been having a slipping transmission since the record setting track day. After a vast search of capable transmission specialists, I decided to go with Level 10 Transmissions, located right here in my own NJ. I have heard their name thrown around in high HP/TQ domestic crowd before, but never knew they were in NJ. From the moment I talked to Pat on the phone, my spider senses kicked in and told me this is the place I need to go to get what I want done, when I want it done, and done right the first time.

      With the help of fellow BB member AKH23456, we made the 2 1/2 hr trip to drop my car off. As AK can confirm, my spider senses were correct. From the moment you spot the large facilities, you know this place means business. We walked in the front door and were greeted by walls and walls of Magaizine featured artciles, write-ups, and pictures of customers and their accomplishements thanking Level 10.

      A warm greeting by the receptionist and few minutes later by Pat himself. Not only did I have more than a few commonalities with Pat, which was nice, but he was genuinely excited about ME bringing my car to him, and my own accomplishements to this point. All of this was confirmed by his energetic fist-bumps when told what my record was, and then again when I told him what AK's AA supercharged M3 had run, ON STREET TIRES.

      So, a few quick photo's of the place as I wanted to get back on the road before traffic picked up, (didnt really save us BTW)

      The walls all the way around are covered with decades worth of accomplishments and pictures of grateful customers


      Small portion of the shop. Not pictured, but to the right is where the real magic happpens and all the transmissions are dissassembled and repaired/rebuilt

      More to come once the project is complete

Basically, how do you want to see how the trans is reacting? layout the scenario the best you can and ill do what I can.
        I think we all want to see how it reacts off of the line under normal throttle to see how the converter engages. Also, the shifting through gears under normal load. Lastly, a decent romp from 2-4 just to see how fast the tranny shifts in comparison to stock under heavy load.

        Does it shift a lot faster? I would think they would need to mess with the software to make it do that. Or maybe they did? I guess we'll wait for details....

        1st through 4th with video of rpm and speedo... maybe a exhaust clip so we can really hear the shift!

        Software they are still working on, apparantly they couldnt do much to it, so i believe im not taking full advantage of what has been done mechanically, but it is definatly faster and street driving is 95% the same, of course a higher stall does add some "delay" but its nothing that you would notice. Ill see what i can do. im gonna wait till later so i can put the gopro on the drivers window and get just the dash for you guys.

        +1 that would be perfect. On a side note i have no fluid leaks and level is perfect. Fluid looked like new and was clear. No burning smell. My shop thinks oil just gets too hot and after a while on high boost slippage occurs. Will flush and put some redline d6 which has a 40f flashpoint over oem oil and add a separate at oil cooler and remove the oem heat exchanger.
        Lostmarine: what oil did they put in your tranny? No plans for an OC? Any comments from l10 about it?
        Also it would really help to have a finned alu AT oil pan instead of the crappy plastic one.

        +1 ... LM, normal load (partial throttle) will be a great addition to a high speed run. in addition to what trevor said, maybe a 2nd gear pull from below peak torque, say 2000 rpm.
