I'd change the fluid to make sure the correct stuff is in the tranny. In the 1970's, Saab spec'd a SAE 70 lube, which IIRC was superceded by motor oil. I'm pretty sure your late 1980's cars call for 5w30 or ATF. I saw a few 99's that appeared to have 85W-90 in them. They shifted much better with the SAE70.
