Not exactly Alex, MTL isn't thinner than D4ATF and I highly doubt MTL would be thinner than Mobil 1 ATF. Compared to motor oil, these are the respective weights and viscosities at two different temps of Red Line tranny oil: D4ATF - 0W20 - 34.0 centistokes at 40C & 7.5 centistokes at 100C MTL - 5W30 - 50.8 centistokes at 40C & 10.2 centistokes at 100C MT90 - 15W40 - 89.2 centistokes at 40C & 14.7 centistokes at 100C (per Dave at RedLine Oil) MTL isn't thinner than D4ATF but is thinner than MT90.

MT90 will make shifting more difficult in colder temps but would provide more protection against break down at higher temps. All three are synthetic obviously so all three provide very good protection against thermal break down. I am not sure what temps are seen on the track in the tranny though.

Thin as possible is the ticket. I've had good luck adding MoS2 to Mobil 1 ATF in my gearboxes. I wouldn't do it if my gearbox had clutch material on the syncro rings. I've done this with both brass and steel synchro ring boxes and they shift very well. Difficulty shifting into first or reverse when stopped may only mean the gears have stopped turning.

What are the options for repairing this damage? A front end respray would seem to be the most radical and expensive. Is touch up paint effective on Avus Blue metallic paint? How obvious is it going to be if I touch up spots and chips that number in the tens? Do detail shops inside or outside BMW dealers address these at all? I've done a small amount of touch up repair in the past, but not to the degree that my car would seem to require at this point. I could also live with it as evidence of use, but there are a few good size dings that I'd want to resolve in any case. Advice appreciated..

Maybe the older types no longer exist, but it is worth making sure you have the udated version. The way I understand it, there are at least 2 types, 91 and 92-. My clutch is not as stiff as the 91 cars. Gary Derian's new clutch is as light as a Honda. It may be a third type or it may be that he installed it well with lapping disc to input shaft and such to make it work smoothly.

I'd highly recommend staying as far away from these guys as possible. Pacific BMW has the M5 clutch kit in stock for $280. I just did a group buy on the UUC flywheels and some of the people that bought from me ordered from Buyclutch.com in April/May and STILL haven't received their clutches.

The bolts also should not be reused, as you experienced, the heads deform on installation. The LSD unit should be placed in a press to take all stress off the bolts during installation, so they can be tightened evenly and correctly. I also use Loctite 270, as per the factory repair manual. Beyond falling out, I've also seen them break heads off, but I believe the two are related, i.e., most of them back out, one doesn't, it's now holding all the stress and shears. The bolts are available from your BMW dealer, I believe the number is 33 14 1 206 924, but can't confirm this right now. My version of TIS lists a tightening torque of 33Nm for the M8 and 47Nm for the M10 (which is found on the large differentials from the M5, etc) Brett Anderson KMS > -----Original Message----- On Behalf Of Robert G.
