915 Euro transmission question

[jacko241]

I was wondering if anyone knew the differences between U.S. and Euro 915? I have heard the gearing is different. Do the Euros all have 7:31 R & P? Are gear ratios lower or higher?

[Geary]

I don't know the minor gearing difference, but the R&P is the same (8:31). The Euro has the oil pump/cooler set-up, which is the main difference.

[jacko241]

I don't think all the Euros have the pump/cooler. I am pretty sure there is a gearing difference.

Just about all Euro's that are non-cat have the oil cooler....

Euro cat cars ( optional...yields a tax break) did not have the cooler.

Final drive were 8:31 I believe...but minor 3rd, 4th gear ratio differences...almost impercptable.

geared slightly higher to take advantage of the extra horsepower

Thanks so much guys for the help. Helps me out a lot!

Gearing is definitely higher. My buddies Euro Carrera has much different gearing than my US 915.

I know that I have seen that info posted here before. Have you tried a search?

As has been mentioned, minor differences in a given year, a little more variation between years.

When I was building my car I wanted a 915/67 or 915/69 or 915/72, al. case, lsd, cooler, these were used on '84 -'86 ROW Carrera

for track use you will probably want lower closer 3,4, 5 anyway.

if you are shopping for a track car trani, check out the classifieds, there are two for sale

would a 3.6 car with a US transmission be better for the track than a Euro geared transmission?

The difference in gearing is minimal, tire choice is more influential.
