having a hard time identifying what tranny i have. i sure its not an ls. dont want to pull tranny and count teeth just to get an answer. my car sits at 3800 rpm in 5th doing 80mph. can you give an educated guess as to which tranny this is. b16 or gsr.

give a few more speeds / rpms in other gears. I am sure this will help those who help you because it is my understanding some 3rd gears are similar.

 

what does it say on the trans?

 

cruise at 80 mph while in 5th gear and tell me what RPM you're in.

if you're right at 4k, then it should be a gsr.

 

doesnt say anything on the trans??????? i will check my rpms in 5th doing 80 tommorow. ill let you guys know.

 

just for the record

my LS tranny sits my ls/vtec dead at 3k at 60 in 5th

and dead at 5k at 60 in 3rd

 

look on the tranny it should say, like p72 or p73


it should be stamped on there

 

ok i was way off, i edited my first post to 3800rpm in 5th going 80mph. also in 3rd doing 60mph im at 4900 rpm.

 

Seems like you have an LS transmission

 

sounds like a gsr cause stock tach's are off by a few hundred rpms and thats about where mine sits and its a gsr cable tranny

 

LS 5th:
80mph @ 3400 rpms
70mph @ 3000 rpms

My tach is DEAD ON 4k when I'm cruising at 80mph.

this also sounds kinda high for an ls tranny. am i wrong?

 

b16 tranny at 80mph is almost in vtec, cant remember exact rpms it was at.

 

I went through 3 transmissions.

GSR at 80 is pretty much right at 4k
B16 tranny at 80 is right at 4300
ls at 80 is at 3700.

check it if you want

set the redline at the rpm you want to see the speed

 

those calculations are with a 205/50/15 tire..

ls is not at 3700 at 80mph.........i drive mine on the freeway everyday 80 is around 3400-3500 195/55/15 ls mesh

 

it's an ls tranny. at 80 mph my gsr tach is straight at 4. my ls would show 3700.

btw, tire and wheel size will not affect the relationship between the displayed rpm and speed. the ecu doesn't know what size tire you have.

are you on crack ????? of course tire size and rim size well affect rpm and speed. the lower profile your tires the shorter your gears well be. the same goes with if you get a smaller rim(unless you compensate with the tire) your gears well be taller if you get bigger profile tires, too. sames goes for rims here too.

nope, no crack. you're right, the tire size will affect the relationship between rpm and speed; i said it won't affect the relationship between the displayed rpm and speed. if you were to check the speed of the car with a radar gun, then yes, different tire sizes will give you different speeds at the same engine rpm. however, the ecu doesn't compensate for different wheel/tire sizes.

 

I have an S80 LS tranny and @ 80mph, my car is at 4k, if not a little over. 205/50/15 tires. I hope I have a GSR trans, but I seriously doubt it. 3.5k @ 80mph? I'm always doing 80 and I've never even come close to that. I drive 35 miles each way to work, all highway.

4k at 80 mph with an ls tranny? impossible. my bro drives a 98 gs, and his car is the same as my 99 ls; 3700 at 80. mine, along with several of my friends gsr's are at 4k at 80 mph. sounds like you do have a gsr tranny.
