whats up guys heres the deal i needed a trans for my ef i did a ls swap into it awhile back and now i needed a new trans so i called local junk yard and asked for a ls trans said thy had one for 300 on my receipt i got it said 93 gsr so i said hmmmm with ys1 on trans sticker pulled my old ls trans out an went to put this one in an clutch was different (old clutch was 2 small )so went and got a new clutch for a 98 + now im stuck if this is RARE LSD gsr trans that i got for a steal.seems like it pulls alot harder and tacking 4k rpm in 5th doing 80 and leaveing burn marks from both tires wen i do burn outs ha any help on this i been stuck trying to figure this out for a day now

 

take out the axle, and if you see that the diff hole is totally hollow, with no obstruction in the way, the tranny IS LSD equipped.
If the diff hole is not hollow and has a bar through the middle, the tranny has a stock differential.

 

and it should have LSD stamped on it

 

it has a bar in the middle but i can see around it. but my big question is it a gsr trans or a ls trans? it seems like it pulls so much harder but i forgot how the long geared ls feels. i know with this trans im tacking 4000 rpm in 5th at 80 mph

 

whats the stamp on it?

 

says ys1 on the sticker cable trans btw

 

Ls.... 3500rpm at 80MPH
GSR.... 4000rpm at 80mph
B16 and Type R..... 4500rpm at 80mph.


or open the case, gsr will have tapered bearings on the diff, ls will have roller bearings

gsr has a 4.4 fd
ls has a 4.2xx fd

count the number of teeth on the ring gear and divide by the number of teeth on the counter shaft

 

sweet man so i got a gsr trans thats smooth as butter for 300 bucks? good deal?

 

Ys1 89 to 91uses cable clutch disc
Ys1 92 to 93 uses the hydro disc I know its weird because its a cable trans but it takes the hydro disc
