How can I tell b series transmisions apart.... they dont have the sticker on the front.... plz help... thx

 

you cant without taking it apart

 

is it installed in a running car?

 

one is not but the other is....

 

if you do a test drive you can use this test

mph at 3000rpm in 3rd and 5th gear

32.6/56.1 --- S1/J1 (JDM 90-91 Integra RSi/XSi)
38.7/66.1 --- S1/Y1 (USDM 90-93 Integra RS/LS/GS)
38.7/68.7 --- S80 (USDM Integra LS/GS/Spec)
30.0/55.6 --- S80 (JDM 98-01 ITR)
35.0/60.4 --- S80/Y80 (USDM GSR, JDM 93-01 SiR)
34.7/56.4 --- Y1 (JDM 99-91 Civic/CRX SiR)
32.6/56.1 --- Y21/S21/S4C (del Sol VTEC & 99-00 Si)
32.6/56.1 --- Y21/Y80/S80/S4C (USDM ITR, 95-97 JDM ITR)
32.6/54.4 --- YS1 (JDM Integra XSi, USDM 92-93 GSR)

you can tell this difference between and ls and gsr but will be hard for similar tranny.. but if it that close whats the difference

 

THX.. giving this a try tomorrow...

 

you can double these number at 6000rpm..
