Rebuilt transmission

After blowing a "transmission seal" I brought my 1992 SVX to AAMCO where I was advised I needed a rebuild of to transmission to replace burned down "clutches" etc. $3,000 later, after I got my SVX back from AAMCO, I noticed a chattering or vibration on hard acceleration from say 15 to 45 MPH. The tech at AAMCO told me thois was just a matter of :greaking in the new clutches", etc and "fixed the problem" by taking the fuse out of the AC slot and putting it into the front wheel drive onlyposition.

Since the AC fuse controls the radiator fan I nearly cracked the engine open from gross overheating, I. E., no fan running led to my temperature guage going out of range before I noticed the problem.

The local Suburu repair shop says no way does a rebuilt tranny's clutches have to wear in b before the vibration/hesitation I experienced will go away. They say AAMCO 's work should be discarded and I should purchase a new tranny from Subaru.

Any comments and advice?
