Transmission choices?

[Dyno4mance]

Maybe this should have gone in the transmission forum....but it is really a race question
Please move if I have posted in the wrong area

Are there any other transmision choices with better ratios available for cars that require the Getrag 260?
Is anyone producing a straight cut gear set for a 325is?
I remember seeing European Ford Sierra 5 speeds by quaife available on maybe VAC or someother vendors site...are they using an adapter plate or have I got my wires crossed?
Thanks in advance

Not sure if this would work for you...

Thanks for that it is sort of what I want ...although that is a used one off that is probably sold by now and it looks like the company that made it are into 135s...is there not a company that just deals with the getrag range of the era
Does anyone speak this language and tell me any more info on this...(Click "BMW E30" tab at the top of the page and scroll down to trans)

I believe www.metricmechanic.com will make you a 260 CR box.

But I also think it is in the $3500 range.

e46 6 speed? e36 m3 5 speed zf?

Will the e36 tranny fit the M20?...any idea of the gear ratios in that tranny?

Metric mechanic trannies will probably offer the best track longevity of the stock-ish options given the work they put into the parts.

As for the 6 speed, it should work with a custom driveshaft, among other things. Since the 260 bolts to an M50 fine, albeit at an angle, it would make sense that the reverse is true as well.

^The 6speed does work with a custom driveshaft.

BierBrenner, has a How To thread on getting a 6spd in an E30.

I'm using a Getrag 240 from a late 318iS. The ratios are a bit closer, as well as having a lower (numerically) first gear. The only fitment problem is that it is rotated 10 degrees relative to the block, so it sits a bit twisted in the car making custom shift linkage and mounts necessary. It IS technically a bit weaker than the 260, but behind your M20, it will last quite a while unless abused stupidly--this does not include track use. Fill it with MTL and go. Mine came out of a 90k-mile donor, and has performed great so far. It's also about 10 lbs lighter.

MTL? I was under the impression these cars trans called for ATF, have to double check the Bentley though.

yeah they do but I always ran MTL in mine. Its what the doc called for :-D

The fluid depends on what transmission label you have (260's), but the zf's take atf.

it doesn't matter. Apparently the only reason some of them came with ATF was to save money. Why keep two types of fluids at your factory (to the tune of millions of gallons) if you can get away with using only one?

my G260 originally came with ATF (~220k). Been running Redline MTL in it for the last 30k, it's been just fine. Personally I would rather run MTL regardless of what the OEM says, ATF just isn't as good of a lubricant.

[gearheadE30]

iirc some have an orange sticker and others have a green stocker. Green sticker ones were supposed to have ATF. It makes more sense to run MTL though.

[nando]

yeah mine is a green sticker with over 250k, and I run MTL
