Hello, I do not own a Subaru as my screenname shows but my friends 1990 Subaru Legacy 2WD is in trouble. He told me when he put it in gear he heard a loud CLUNK and it would not move but the speedo would go up. I am not too familiar with Subarus so I found this and am turning to you guys for assistance. Thanx for all your help!

Auto or manual tranny? That would help.

Oh sorry, Auto Tranny

Hmmm,

 

I would venture to say that if the speedometer is moving then some parts in the A/T are working, but other parts aren't.

 

My conclusion would be that this is not good. Maybe he can find a good tranny in a junk yard.

Check to see if he wasted an axle.

Torque converter? Has he checked his tranny fluid level lately?

hopefully fluids not light grey(bad)/red(good)

 

couldn't he have popped a cv joint too.

Yep, I would say check the axel also. Before I bought my subie, my old sentra had the same problem. I would put it in drive, and only here clunking. Initially I thought is was a tranny problem, and since my car was an old piece of crap, I decided to sell it for $100 instead of fix the tranny. It turned out to be a broxen axel, but too late, I already sold it. Anyways, can't complain, love my subie but the wallet's hurting!

Gotta be an axle.

 

The speedo is driven off the differential gear. So if the speedo is working, that means the tranny is moving and working.

i was under the impression that the speedo was driven off one of the other more internal shafts of the tranny if not the pinion it self...

but it is possilbe i am just confused..

if i am not then would it not suggest at least a bunch of teeth have decided to relocate from either the ring gear or the pinion gear

..

but he did say clunk and not crunch/grind type noise

so i will go on the assumption i am confused and tired

Look at this scan
