95/92 manual tranny swap?

[dbur]

Hi,

I have a 1995 5 spd Legacy wagon with a bad tranny. Motor turns and clutch works but car won't go. It had some gear grinding sounds for a while whenever we let off on the gas before failing completely.

I have a good 1992 tranny than seems to be almost identical, though I haven't yet been able to confirm that.

Both cars had the same motor. 2.2L H4 SOHC 16V

Tranny numbers:
TY752VA2AA (92)
TY752VAAAA (95)

I also found this info:

1992-1994 AWD non-turbo MT Legacy
4.111 Final Drive Ratio

This matches what I have found for the 95. There seems to be a tranny chart that goes back as far as 94. It says:

Model Range Trans. Code 1st 2nd 3rd 4th 5th 6th Rev. T.R. F.D. Center Diff. Type Front Diff. Type

US Legacy Outback MY94 TY752VAAAA 3.545 2.111 1.448 1.088 0.780 N/A 3.416 1.000 4.111 Viscous (4kgf) Open

In any case if they don't match I could always just swap out the rear diff for the one that is now matched with the 92 tranny I want to use, couldn't I?

How can I confirm if this swap will work, or can be made to work?

Thanks.

Welcome to the BBS.

I believe the 92 tranny should work in your 95. The 92 MT non-turbo trans does have a 4.111 final drive ratio.

I measured the ratios in each by jacking the cart up and rotating the rear wheel while counting revolutions on the drive shaft.

For the 95 I got 3.95 and for the 92 I got 4.11. Pretty close to what you said. In any case they are definitely different.

I'm not understanding why the TY752VAAAA can be listed with a 4.11 rear diff for the 1994 model year.

In any case I assume this swap can work if I also swap the rear diff with it. Is that right? Would the speedo gear or anything else have to change as well?

Just checked the 95 manual and it does have a 3.90 final drive ratio. So you'll need to swap the rear diff over to match the 92's 4.11.


The transmission code doesn't really give you any meaningful information regarding final drive ratio, only gives you information on the year & type.

I haven't found the trans codes to be overly informative, and there's so many varients, so it adds to the confusion.

Bottom line, swap the rear diff and tranny from the 92, and you should be good.
