I got this tranny from a friend and I've been running it in my boosted car for awhile. But I drove my brothers car last night and he has an all motor ek, and his car will cruise at 70mph at about 4,000 rpms. In my car i am only at about 3200 rpm's. Should I assume I have a LS tranny.

 

Ditto, unless you have LS 5th gear.

 

DOH!! This bites lol.

 

yep ls hope you didnt pay to much for this

 

No, I didn't. But I thought it was a GSR. Oh well.
