I have a 1998 Subaru Forester with a bad transmission, no reverse and metal shavings in the pan, i found a 2001 forester with a good tranny for 500 bucks Just wondering what snafus i may have, or will these bolt up and plug in. according to the vin # they are both 4eat transmissions. but looking at them side by side they are definitely different in shape and size. the transmission codes are
the 1998 forester TZ103ZJ1AA
I am trying to figure out the gear ratio cause i hear if that matches i may be all right and maybe swap the speedometer sensor. is this true?

They are not compatible. The 4EAT went through a major revision in 99 and you can't easily interchange them.

the 98 forester has a 4.44 final drive ratio.

you can use any trans from a 96 - 98 2.5L, outback, GT, LSi or forester. if you use a GT or LSi your speedo may be off a little.

you can find good parts at www.car-part.com. you will have to search each year and model separately. sort by distance to see what is close to home first and then by price just to see if there is a deal somewhare. shipping will cost about $150 so add that to any far away trans price.

note, just so you know: a 95 - 99 legacy / impreza (2.2L) trans will work but you will need to swap in the matching rear diff as well. and this will change your power curve / fuel economy.
