Anyone have any experience with the Renntech transmission "upgrade" they list for W210's? I'm wondering exactly what you get for $1,300.00 and if that's a good idea on a supercharged 55. They also list an oil cooler for the trans and the engine. Feedback anyone?

I dont think the Renntech offers a transmission reprogram for the w211.

W210 E55.

Well, the skinny from Bob Brady at Renntech is that they actually add clutch packs to increase the max HP and torque the trans will withstand. Unfortunately, that means pulling it out and shipping it to Florida for them to perform the mod. 2-3 weeks shop time, plus a week shipping in each direction! Guess I'll see how well the stocker holds up to the blower for now.

european car mag did a test with an m3 and changed all fluids engine, trans and rear diff with red line syn racing oil and got 7hp consistantly

Not looking for any additional HP, just want to keep the trans alive behind all the power. This is a tried and true method of beefing an auto trans. Anyone tried redline or anything else like Amsoil in their MB tranny?

go to the redline site and click on their link for trans fluid. they have fluid specific to mbz which claims to do everything you are asking about
