Trans Ratio ID ?

Featured Replies

This is another torque binding question, I have read the forum on this issue from the time I joined the board and have seen it discussed that some have developed binding after a transmission replacement, I too have now discovered that it was about that time that I developed the same, and now have the strange feeling that the trans and the rear diff are not the same ratio. I did look and find that the rear was a 3.900 ratio and now for the $100 question.... what ratios were used in Subaru Transaxles ? I have a 93 Legacy SW and to the best I can recall the new trans was from a Impreza unknown year and the garage that replace the trans has went out of business.I did find some numbers on the trans ..TZ1022A3BA-G9 829464, can it be ID from this number ? or does it mean anything at all. I see that many talk about changing the rear diff to match and that's where I'm headed if I can ID the ratio I need.

 

Thanks A Million ....

 

Congrats to Nipper on the 5000 posts.... You are a true wealth of Subaru knowledge !

Almost all early non-turbo Legacys were 4.11. At that time, the only Legacys with 3.9 were turbos. I can look up that number tomorrow at the shop to make sure (if I remember).

I bet that a Subaru dealer could look up the transmission in question and tell you what it should have.

 

I've been told by a Subaru garage that non turbo 90-91 Legacies have 4.11 gears, 92-94 have 3.9, and then they went back to 4.11 in 95. I don't know if that's 100% correct.

I've been told the same as snowman, but I have my doubts about the subaru dealer. When I first asked them about the tranny ratios, they said "we only replace parts with new factory parts" sO I said, you know I figured a subaru tranny was a factory part and hung up on them.

 

Do a search, I had a thread about this that I started a few months ago.
