i have a question about my tranny. i hit the freeway and im going 80mph. im on 5th gear and my idle is at 4k. do i have a b16 tranny? or is it a stock LS. oh my car is a 91 LS. just got it. everything is stock. and it has a chipped ECU that revs up to 8. if that makes any diff.

 

Sounds like a gsr tranny with 80mph@4k rpm. But it seems like you have a cable tranny since its a '91 so i think its unlikely you have a cable to hydro conversion. Revving an LS to 8k rpm isnt smart either.

 

ooh i see..thanks...yeahh at first i didnt know it went up to 8k rpm...i just bought the car..probably goin to take that out haha

 

sounds like an ls trans to me. my 90 ls ran like that, when it was stock.

x2...deff a ls tranny

 

check and see if the VIN# on your firewall and the VIN# on your trany match, if they do then it is your stock ls transmission.

 

i used to have a b16 tranny on my gsr i made a road trip doing 80 and i was at like 5.5.. yeah vtec for 3 hours with a test pipe is <u>not</u> fun

 

ill check on the vin...when i drove my cuzz LS...it rev at 36-3700 rpm at 80 mph...the guy also said he changed the tranny...but he doesnt know which one lol

 

your tranny is deff a ls....thats exactly where im at 80mph at 4k with my DA

 

i searched a little around google. found most threads about gsr rolling at 80mph is at 4k. cant really find an ls thread. should the ls be the same as the gsr?

 

there's a few tranny speed calculators around, just google it and put your info in, it'll tell you what rpm and mph each type of tranny will give you

 

i just tried it on the freeway again...at 4300 i hit 80mph. around 4000 i hit around 76...weird?...any LS owners get the same?

 

Ive driven a civic with a b16 swap and it was doing close to the 4500rpm range at 80mph. My gsr is at about 4100rpm at 80mph. I would think an LS would be somewhere in the 3600-3700rpm range.

 

are you serious?

i hope you dont expect someone type in the info too, you lazyxmofo

 

whats the calculater going to do? lol. ...its going to tell me my gear ratio. but im wondering if other ls owners get the same rpm as mine.

 

..........sigh.........


put in the info for a ls tranny (ratios and FD) and your tire size, it'll tell you what mph and rpm you should be at if it was a ls tranny


then put in the info for a b16 tranny and your tires size, it'll tell you what mph and rpm you should be at if it was a b16 tranny

then compare the data with what your seeing and you'll find out what you have,

..........seriously

 

Wow alot of misinformed people here...

Ls cable tranny will have you around 3200rpm at about 80mph, a cable gsr tranny (also known as a ys1) will have you around 3750-4000rpm at 80(ish). If ls trannys were at 4000 rpm when at 80, then gas mileage would be horribly for stock integras and the ls 5th gear wouldn't be so popular about saving gas...

FYI, this is PERSONAL EXPERIENCE. Not what I have heard/read...I have driven stock ls motors with both trannys...

b16 tranny will have you at 4500rpm+ at 80mph...I think hydro b16 is a little higher...
