I did some searching and found the JEBA mentioned here: http://www.ultimatesubaru.org/forum/showthread.php?t=70457&highlight=JEBA

 

I don't have access to either car right now. One is the GF's daughter's SUS, the other is an OB that I'm thinking of looking at to buy that's 1 1/2 hours away.

 

For the 99 2.5's it seems(I'm asking for confirmation and help here) that the early 99's received the TZ10272DBA transmissions. Later year 99's received the TZ1A27JEBA transmissions. The price of these used varies by about 1k.

 

In the above link describing transmission there is talk about how many bolts/pins where the engine and transmission meet. Neither car is within 50 miles of me and there aren't willing or reliable folks for me to talk through looking for engine bolts.

 

Anyone have a suggestion on replacing the JEBA with something else? I know the SUS has the JEBA because I got the code last year when she first started having problems). The OB I'm assuming it's the expensive tranny since it's for sale. I've also passed on a few of these within the last year due to the price of the JEBA.

 

TCU and/or rearend issues that may be cured with matching TCU and/or rearend?

 

Any other wiring or sensor issues?

 

Anyone done it?

 

I seriousely doubt that this will be as easy as a 2.2 for a 2.5 swap but with 1k price difference I'm definately looking for options.

 

Thanks,

 

Dave

the jeba trans is a phase 2 transmission. it has a different wiring connector and more speed sensors than the TZ102Z2DBA. if you are replacing a jeba trans, you need jeba or later. the earlier trans is not compatable.

John,

 

Thanks for the reply. The tranny's that I looked up for OB/SUS for 2000 are almost as expensive as the JEBA. Unless I get one for a 2001 L model then they are cheap - like 350. Perhaps ratio issues or TCU issues?

 

 

I hate to spend 700-1k on an incorrect year tranny and potentally have issues installing it.

 

Perhaps there is no good, clean, inexpensive way to handle bad JEBA's. It's a shame because I've passed on some nice cars and the GF's daughter doesn't have that kinda money.

 

Anyone rebuild these reasonably - or would shopping alone be prohibitive?

For the unwashed and uninitiated among us . . . what the heck is a JEBA?

TZxxxZJEBA is the part number for a 99 (late) outback trans. it was the first of the phase 2 trans in outbacks. ( i think foresters got them earlier?).

 

i don't have any experience with 'oo and newer so i can't comment specifically. but generally when subaru made a change they used it for several years. but in regards to the 99 and later trans. the 'style' of the trans part number (...JEBA) was only used late in 99. in 00 they went with a different par number, different style.

 

the interchange software at www.car-part.com apparently only compares part numbers. it will never tell you a 98 trans will fit and work in a 96 outback, but it does. the question is ... will a 2000 trans work in a 99 (late) outback??? i do not konw for sure, but i suspect it will.

 

any one have any experience here??

John,

 

car-part is always where I start my search (and thus compatability search).

 

From USMB I know there is a lot more interchangeability and substitutability(2.2 for a 2.5) than car-part shows.

 

Just looking for better (lower cost) options for the JEBA.

 

Thanks to all who are pondering this or may have done a swap for a JEBA.

Here is how you tell the difference...

 

All OB had a 4.44 final gear ratio, so if you find an OB trans you are set. BUT The other problem is, 99 are a mixed year for the SUS. Some still had the phaseI 4eat, like mine did while other got the PhaseII trans. The way to tell them apart easily is to look for a spin on extrnal filter. These spin on filters are found on Phase 2 transmissions ONLY... No Phase I had an external filter... Good luck, hope this helps
