What type of transmission fluid is best for 1986 Testarosa. ( Redline ?)
REDLINE 75/90 NS If you want it to shift good it MUST be NS If the limited slip clutches in the differential start to chatter on tight corners squirt about 4 ounces of LSD additive into the transaxle and drive it for 50 miles to see if the chattering went away. It will continue to shift well as long as you use the additive sparingly. BTW, this worked just as well on my 308. Steve, I'm north of you about 90 miles. ...................
