04 Outback H6 LL Bean 124k - has shifted hard from 2nd to 3rd since the day I bought it.  I've flushed the transmission by draining fluid, refilling with fresh fluid, and repeat 3 times.  I've also replaced the remote trans filter with OEM filter.  It's also received the "special" additive from Subaru that's suppose to help with the transfer clutches sticking a little (a whole different topic but should have nothing to do with 2-3 shifting).

 

Doesn't matter on temp the car always shifts harder than it should form 2-3.  Took it to local renowned sub shop and they said replace the trans.  Don't believe it.  I'd like to swap the shift solenoid first.  How and where can I find the exact solenoid I need?  Is it a pretty simple job?  I've replaced the H6 HG myself so I can't imagine a shift solenoid is too complicated??

 

Any help would be greatly appreciated!!

 

Thanks

Subaru transmissions are hard shifters. I would first check to see if the shift resistor is still in good shape. The solenoid wont do much with shift quality as it either opens or closes, If anything it would make a slower shift. There are usually accumulators and delay valves that have more to do with it then the solenoids, and on a subaru the solenoids are fairly robust.

 

Lets look at this a little diffrently, how are the transmission mounts?

Given how my '03 TCU learns bad habits, I would say 1st disconnect the battery and make it forget.

That does wonders for the H6 4EAT 4-3 downshift REV-BANG
