KA620KC Posted July 27, 2011 Report Share Posted July 27, 2011 OK guys I've been searching the net and can't seem to find any definitive answers. But does anyone (Datzenmike maybe??) know if there are any major differences between a single cam engine transmission and the twin cam engine transmission?? I know physically they look identical except for a few sensor differences. But are there any differences in gear ratios? My reason for the questions is because I ended up destroying the input shaft on my tranny from my twin cam engine and was given a transmission from a single cam engine setup. It may be just me but the single cam transmission seems to be a bit slower or maybe just not as torquey as the trans from the twin cam. Am I just "thinking" they are different?? And how difficult is it to rebuild one of these transmissions? Quote Link to comment
HRH Posted July 27, 2011 Report Share Posted July 27, 2011 You're killing me smalls, this should be in General Technical. Ratios are most likely different, other than that everything else should bolt up, but wait for Datzenmike, he may have more info. Quote Link to comment

ggzilla Posted July 27, 2011 Report Share Posted July 27, 2011 any major differences between a single cam engine transmission and the twin cam engine transmission? Are you asking about the transmissions from KA-equipped Nissan trucks?

( Fawked Up Beyond Any Repair ) Tisk Tisk ,,, were you having some fun when you destroyed your tranny ? :D hehehehehe.....alright heres the story..... Yes I have been raping the shit outta the truck..... :cool:. I assumed at first that my throw out bearing was going bad due to the fact that it was only making noise when the clutch was released. I didn't change it right away but figured I could get away with it for a little while. Well I took the truck for a 120 mile trip and on the way there the trans started to whine and howl really bad. I babied her back home and lifted her in the garage. I pull the plug on the trans and hmmm......only half a quart of fluid comes out :mad: what a freaking dumbass!!! I completely forgot to check the trans fluid when doing the swap....arrggh. Yes I know let the flaming begin. But getting back to it I pulled the motor to change the "throw out bearing" and found a completely destroyed input shaft. I'm thinking possibly, maybe, coulda been from the lack of fluid hahahaha.

It is a Twin cam DE from a 92 240sx as was the original transmission. My replacement trans is from an unknown vehicle but was definitely from a single cam. Quote Link to comment
