is there a difference in a a1 and ys1 tranny?

[competitiveaudioman]

just wondering cause my a1 took a dump on me and i was going to swap my ys1 in my 90 integra. will i run into any problems?

The a1 has longer gearing then the ys1. Not only would it fit but your acceleration would improve. Your mpg would suffer slightly but I don't think it would be noticeable since you'll be ripping first gear anyway now.

well good then. i dont know if you know or not but the ys1 came stock in a 93 integra so its not the short geared gsr or b16 tranny.

It came stock in the XSi Integra that was powered by the XSi B16.

my 93 integra just had the b18a in it. it was a integra special. thats why im assuming they are both the long geared trannys

I was just looking in the reference section and your right. There were two YS1s. Why make different transmissions with the same code though? weird.

i know right? i was so exited the first time i seen the little orange sticker on there and it said ys1. but oh well. i got my tranny in and everything bolted up fine. still didnt help my problem tho. i lowered the car and now it acts like somthing is binding or grabbing but nothing is rubbing or nothing. it has a strong hesitation under acceleration. does anybody know what this could be? ive replaced cv axles, and tranny. nothing is rubbing
