Question Difference in RS stock trannies

I am going to have to replace my tranny soon, and want to know the differences between them. Are there? I know MY98 have a 4 bolt housing, but besides that. Are the guts any different? I know that Tylmetr(?) is selling a 98. Joel, will the MY98 bolt right up to a MY99?

TIA,

MattC

Hello,

Pat's done it that way on his cars. But, the answer is yes. Pat and I disagreed on the difficulty level of doing the swap, but the main difference is the mounting of the starter, which you can accomodate on the '98 to '99 direction with a drill bit and a round-OD allen bolt. I can't remember what it takes for the other direction.

I guess a search for our last discussion might come up with the answer.

Any idea on how hard/costly changing from an auto tranny to a manual would be?

Cause if its cheaper than trading in my MY00 for a standard MY00, I'd rather do the swap.

It won't be cheaper. Keep your automatic 00 and either get a 5spd impreza turbo or get a 5spd RS from someone upgrading to the turbo.

Hello,

Just some thoughts - the changeover requires changing plastic bits on the inside, parts behind the dash, the tranny itself, the starter motor, the EGR system, adding in wiring for things like the VSS which is different from auto to stick, etc etc etc. Lot's of work. More work than the depreciation on your car over the period of time you've had it (since yours is a MY00). It'll be more profitable to sell and buy a new car, sad as that sounds.

But do you know if the insides are the same? I don't want to buy a tranny that is worse than my stock one.

Hello,

The '99+ tranny case is a new, stronger case that is designed to flex less than the previous 4-bolt designs. The internals are also different. Front and center diffs are designated as pre-99 and post-99, so there is a definite difference. Which is stronger? Well, since Subaru was making the case stronger, I think it's safe to assume they made the internals stronger if they bothered to change them.
