I'm ready to change the fluid and have a few questions: Looks like it will take 2.9 qts. for a fluid change for the trans/diff; what do you guys recommend? I have had good results with the ACDelco Synchromesh Trans fluid friction modified Semi- sythetic. A lot of the S-2000 track guys like it. I'v also used the Redline Synth. products in Hewland box's, usually using the shockproof superlight. I'd appreciate hearing from Prime members. Thanks, Tomrev
