Yup, we do. It just doesn't have the "NAG1" designation. It has the Mercedes designation of "W5A580". but it's litterally the same trans save for the srt having a bit more aggressive shift schedule

Just put in a mopar or paramount performance tcm and it'll shift better than the SRT too.

Re: 3.7l performance love

What about swapping in the AMG "blue top" solenoids? From the little I've read, they should firm up the shifts and hold the gears a bit higher. They're not really on my radar, but for you street guys they sound like a decent upgrade. Jeff, I kind of assume you've already done these with all your mods? Josh, maybe you have too if you're running the NAG1, can't remember which trans your monster is married to...

I'm running a 545rfe with a couple tricks up its sleeve. But I've heard mixed feeling on the blue top solenoids for the nag, but they are an inexpensive and effective way to firm up the shifts a bit, however I don't think they'll hold the gears for longer, that's all in the shift points in the tcm. I think if you can afford it about $4-500 going for an upgraded valve body would be the best easy upgrade you can do to a stock trans.

Jeff can you change line pressure with your tuner? I wish I had some way of controlling it on mine but the Diablo doesn't seem to have that option...

I haven't yet. But I have considered it and am considering a few trans upgrades soon.

I can change anything bro. From ramp times to shift speeds even the torque management and adaptives are not even safe. I've already got a solid tune in it for daily use and one wicked one for drag down at the track
