How can I tell the difference between ITR trannies? I want to know if one I'm about to buy has the 4.400 final drive or the higher one...

the number is: S80-3095669

 

If you can open the casing just count the teeth of both gears and devide the big gear by the small gear.

If you can't open the casing, try to put the tranny in fourth gear (1.107 ratio) and turn the input shaft. Count the number of revolutions needed on the input shaft to get one revolution of the output shaft. If the tranny as a 4.4 final drive you should need 4.4*1.107=4.87 revolution on the input shaft, if it is an ATS 4.929 FD you should need 4.929*1.107=5.45 revolution, if it is a JDM 4.72 FD you should need 4.72*1.107=5.22 rpm...

cool...

looks like its a 4.7 FD.... any thoughts on boosting this tranny? How about boosting it hard?

 

you might want to build the block first before boosting it hard..

I need to go back to jdm school because I have no idea what he just said.

 

of course... I just wanted to make sure the tranny won't be my bottleneck for massive boost

 

That gearing isn't going to be much help, LSD will though.

 

LOL
get a LS tranny in that case.

 

there is a post in the TECH forum, you can find your answer there, but I'll cut-n-paste for ya-

"Finally, if there is some question about whether or not you're S80 has 4.4 final drive or 4.7 final drive you can check the transmission housing. The code "4jhd" means 4.4 final drive was offered as original equipment, while "ne3" signifies 4.78 final drive. "

HTH
