i got this transmission from a wrecked car in which the transmission pan was dented. It did work and drive poorly after the accident. It's for a 2002 VDC H6. Two of the solenoids under the transmission pan have completely cracked where the electrical wiring harness plugs into them.

 

if the solenoids are impacted - is there any other possible damage or probably just the whimpy connectors?  the connectors are part of the solenoid so it looks as simple as install some new (used that i already have) solenoids with good connectors and off we go. 

 

but i'm unfamiliar with what those solenoids do and if there's any other possible repercussions.

 

i'll probably swap the wiring harness as well (looks easy) and the internal screen filter which also looks like it may have been lightly touched too.

I would say the chances are good the valve body is OK. If you can pull the solenoids and give it a good visual inspection I'd say you can be sure.

Bigegst concern might be if you pull a solenoid and you see it may have loosed chunks into the valve body. Not likely, but something to check for.

I recommend to replace orings on the replacement  soiliniods and should be good to go

thanks, will do, getting part numbers

 

Solenoid Orings: Lock up duty (blue)806920040

Line pressure duty solenoid(Red) - Oring #1 806920040

ATF temperature sensor isn't shown on opposed forces.

 

If you're replacing all the solenoid orings it is:

(4) 806908130

(3) 806920040

(2) 806904030

 

There are 3 external sensor orings: 806913070

Wiring harness oring: 806912140

 

This looks fairly generic for all 00-04 automatic transmissions

VDC and 4EAT transmissions (not front diff and rear extension housing) appear identical....maybe there's really not much difference bewteen VDC and 4EAT transmissions?

Is the VDC front diff different? Thought it was the same.

 

I am pretty sure 4EAT non-VDC and 4eat VDC are identical except for the rear housing and the VTD center diff with VDC instead of the mpt.

All the magic is in the TCU and the center diff.

Is the VDC front diff different? Thought it was the same.

 

yes - but the final drive ratios are different, 4.11 for VDC and 4.44 for Outbacks. 

 

i looked it up on opposed forces and i think some impreza's share that 4.11 front ring and pinion set.

 

so what this means is that by swapping a front diff and rear extension housing one can use any 4EAT transmission in a VDC?

that's comforting since the VDC's are so hard to find and expensive.

Oh, that's why I didn't catch it- I was thinking vdc/non-vdc 4eats that were mated to an H6, all the H6 outbacks that gen have the 4.11s.

my bad, i was forgetting the non-VDC H6's in my comment even though i own one of those too. LOL

 

so my H6 VDC and H6 non-VDC vehicles have interchangeable transmissions..minus the rear extension housing.  fascinating.  

 

when i replaced the transmission in my 2003 non-VDC H6 a few years ago i think folks were saying VDC and non-VDC were not interchangeable.

The TCU and much of the car harness are different for VDC.

 

You can put a VDC trans or just the rear bits into a non-VDC car, you just need to control the lockup clutch manually. The mpt in the vdc trans is designed to be locked or free, not to be partially slipping. It is the same size in diameter as the non-vdc MPT but has fewer plates.
