hey i just wanted to know at 3k rpm what is your mph in 5th and 4th gear on a gsr tranny? i just wanted to know because i was looking at a gsr and i think it has a ls trans, but the owner kept telling me its not. i know a gsr trans redlines 3rd gear at about 90 mph, but i didn't try that because of traffic. tried to look for the code on the trans but it was cover in oil. also what is the code on the gsr tranny.

sorry, if this has been posted lots of time before, but i did search but couldn't narrow it down. thanks

 

I forgot the code but I know the RPMS in 5th are easy to calculate

4K = 80MPH
3.5K = 70MPH
3K = 60MPH

Thats right

 

I have a gsr tranny on my LS, and at 80 mph, its about 4k-4100 rpm. 60 mph is about at 3k rpm.

If you are doubting the seller, then i would suggest not buying from him.

 

thanks guys,
