subasab Posted June 4, 2008 Share Posted June 4, 2008 Hi all, still stuck with my defective H6 tranny on my 2002 H6 OUtback. Whille searching for a solution, i came accross some reading mentionning this: A) Subaru H6 tranny uses many parts from Nissan Pathfinder and Mazda MPV tranny Some retrofitted the H6 engines with some older Subaru transmission or the opposite : a H6 tranny on an older engine. Is any of the above might help me find a solution? H6 transmission are a hard thing to find on he used market. IF YOU HAVE A USED H6 4-AUT TRANSMISSION, DROP ME A LINE. Thanks!

Manarius Posted June 4, 2008 Share Posted June 4, 2008 You could use a WRX auto or 5MT. They could handle the torque and power...but you'd need the matching rear differential. Link to comment Share on other sites More sharing options...
Numbchux Posted June 4, 2008 Share Posted June 4, 2008 I've never heard anything about subaru trannies sharing parts with nissans or mazdas, but I suppose it's possible. but, all subaru 4EATs (that's 4-speed Electronic Auto Trans) are almost identical in design. only differences are gear ratios, and there are a few different designs for the torque converter (just means the converter and flex plate have to match the trans). so any subaru 4EAT will work, provided you have the flex plate, TQ, and rear diff (might not need those things....but it might be cheaper to get your hands on a whole car). also, while you're in there, add on an external trans oil cooler, this will greatly increase the longevity of the new trans.

zukiru Posted June 4, 2008 Share Posted June 4, 2008 rebuilt svx transmissions come in a Nissan box these transmissions are used in awd Pathfinders I don't know which years though. Link to comment Share on other sites More sharing options...
nipper Posted June 4, 2008 Share Posted June 4, 2008 Subaru and Nissan's share quite a few parts. The fact that nissan got the contract to rebuild subaru trannies doesnt mean anything. My engine bought from subaru was rebuilt by a (forget the name) over the road HD diesel truck mfg, yet i dont claim it to be a semi nipper Link to comment Share on other sites More sharing options...

zukiru Posted June 5, 2008 Share Posted June 5, 2008 we're both right... it's just the internals that are shared by the trannys and they Are made by nissan.. Link to comment Share on other sites More sharing options...

Numbchux Posted June 6, 2008 Share Posted June 6, 2008 5-speed manual swap FTW!!! SVX guys do it all the time. and then realize why subaru never offered a 6-cyl + 5MT combination......they can't handle the torque. 6MT or auto. Link to comment Share on other sites More sharing options...

Kostamojen Posted June 7, 2008 Share Posted June 7, 2008 and then realize why subaru never offered a 6-cyl + 5MT combination......they can't handle the torque. 6MT or auto. What torque? The 01-04 H6 has less torque than an 02 WRX, which came with a 5-speed, and the 5-speeds have plenty of upgrades if you think thats an issue, or screw it and go straight for an STI 6-speed...

Numbchux Posted June 7, 2008 Share Posted June 7, 2008 go straight for an STI 6-speed... yea, the EZ's aren't exactly torque monsters, but they peak lower and sooner than 4-cyls. I don't know anyone who's done a 5MT swap into an EZ30D car, but I wouldn't do it.... Link to comment Share on other sites More sharing options...
zukiru Posted June 7, 2008 Share Posted June 7, 2008 they do 5mt swaps into EG33 cars all the time. I'm not sure how this would be too different. (but I already had a little crow in this thread so go easy on me.) Link to comment Share on other sites More sharing options...

I'll be doing it here soon... hopefully later this month... well kinda... by EZ30D car, more like a car with an EZ30D :-p Link to comment Share on other sites More sharing options...

I'm not sure how this would be too different. know anyone who uses all 6 cylinders and has had it last more than a year? I know one guy, but he drives like an old woman...... I'll be doing it here soon... hopefully later this month... well kinda... by EZ30D car, more like a car with an EZ30D :-p I'd be worried, but it'll help a ton that your '6 weighs what, 700lbs less than the outback?

boxerbob Posted June 7, 2008 Share Posted June 7, 2008 and then realize why subaru never offered a 6-cyl + 5MT combination......they can't handle the torque. 6MT or auto. yeah but about every SVX in the world needs even a new auto by 100k miles and keeps eating them faster from there. there was a trick to the 5spd thing the guy who did the first one told me. he lives in somerset,ky and has i think 5 subies now. had 2 svx a couple years ago both 5spd swapped. he also did a 3.3 into his XT6. i say f*** it. 6spd or bust!

H6 outbacks roll in at 3770 lbs.. I'm more at the 2400 lbs or so... +1 on Huck being the man... Don't really recall him having transmission issues....
