Long story short...I just changed my 2000 Road King transmission fluid using Royal Purple Max Gear 75W90. After about 500 miles or so, I put the Road King on the lift, started her up and engaged 1st gear. There is clearly some noise coming from the tranny case (right side of engine). I would call it some mild clatter, but certainly concerning. It doesn't appear to causing any performance issues.
The label of the Max Gear says "Max-Gear is recommended for use in truck and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid."
After some careful reading, I am seeing that the forum generally recommends a GL-1 fluid in the TC88 5-speed transmission>>Spectro 75W140.
The transmission is all stock with 17,500 miles. The Road King has SE (K&N)Stage 1 A/C, Wild Pigs exhaust and EFI (Dobeck), and I have had Andrews 26N cams and hydraulic tensioner setup installed. I am loving the setup, it's running great, just concerned about the racket in the transmission. (I didn't hear it from the seat due to the mufflers)
My question is "Have I put the wrong fluid in my tranny?"
A fluid change would be an inexpensive solution. Could this be a solution to the clatter?
All feedback is appreciated.
