Brad,
When assembling the bell housing to the gearbox you should be using a
sealant on the very bottom bolt and a copper washer for a good seal. Scroll
seals are a misnomer, "scroll delay" is more like it. The positive seal used
on the GT-6 nose housing is a spring loaded positive seal and spots some of
the problems. Of course the input shafts are different sizes as are the TO
bearing carriers, but there are ways around this. Glad to provide details.

Amici,

Immediately after installing the new 1500 single rail 
trannsmission with J-type OD in Susan's spitfire (early last 
year) we started experiencing oil leak problems.  While at 
Mid-Ohio Tony Drews pointed out one of the problems and 
we rectified while that still at Mid-Ohio.  (thanks Tony!)

However, even though the problem isn't as bad now leakage 
still takes place from the front of the tranny.  

My proceedure has been to top transmission up with oil from 
the side of the box and wait for all the excess to flow out 
before putting the plug back in.  During the next race oil 
starts dripping down onto the exhaust pipe and creates a 
small amount of smoke, enough that the corner workers are 
continually scrutinizing Tristan.  There are oil spots under the 
car in the paddock that average about 3" in diameter after 
every race.  If I don't top it up it eventually stops leaking.  The 
transmission still seems to work fine at this point and the OD 
engages and runs just fine as well.

So the question is, do I just let the transmission seek its own 
level?  Or is there something I'm overlooking that could be 
corrected.  This type of transmission uses the scroll type  
seal on the input shaft to keep the oil in the gearbox.

Any BTDTs out there?!!!  

Thanks,

Brad
