no saab never used straight cut gears in their rallytrans. but they where wider gears and no helical. it had a longer(higher ratio) 1 gear and tighter between the other gears. but there is a company in sweden that build straight cut gearkits for the old 900 with good clean dog engagement.
@xReventonx im also looking for a safe tune for my 9-5 aero auto.
from what i heard HP isnt the problem its Torque.
after 410nm or about 310ish Flbs of torque reliablity goes out the window with the autoboxes i cant confirm this though as all of the big hp 9-5's are manuals.
and i know auto gearboxes have stonger torque limiters. thats why 5 speeds have the overboost function and manuals dont.
but from what iv read the autos will outlast the manuals in stock form wich is cool for dailys
I currently race a c900, and i work at a shop that only deals with saab, i have beed looking at people tuning saabs for the last 3 years of my life, and i can honestly tell you, the best fluid for the tranny is redline MTL, and a tranny oil cooler. it doesnt matter what oil you use, or what you do to the engine, the transmissions (non chillcast ones) will flex at over 350 hp (400 ish ft lbs of torque) the cast itself flexes, and moves the input/output and the cluster shaft apart, removing teeth.
the engines can take ridiculous horsepower, but the trannies cant, ive already seen 2 grenade, havnt had one go on mine yet, but it will soon. also, a turbo on the nonturbo block leads to blown pistons/cracked block. the 2.1 pistons are weaker, and the walls of the block are thiner. best bet is to use a 1984 cc block, and PRE APC pistons, a 2.3 head from a 9000, the turbo from a 9000 Aero and a 3 inch intake and exhaust.
saab 900 (classic ones) have problems with drag starts, they tend to grenade with high horsepower.
he may have been trying to save the tranny, although i dont know of any C900's with that much power. there are a few at almost 400 at the crank, but none that high

the problem isnt the case, its the gearset, the rally boxes used straight cut gears,
