Overview of Spectro Heavy Duty Platinum Full Synthetic 6-Speed Transmission Lubricant - R.HDPG6
  • This unigue lubricant was developed for Harley® owners who were unhappy about their noisy 6 speed transmission.
  • It provides smoother shifting, reduces fifth gear whine and eliminates clunks.
  • Spectro's proprietary formula uses G4 Technology, special additives that provide additional anti wear protection, higher film strength between the gears, and reduces drag while extending gear life.
  • High loads and extreme heat do not affect the oil, so it performs excellently when pushed hard and long.
  • A.P.I GL 5 rated.
  • Dyed red.
  • Exceeds all known OEM and Harley Davidson® warranty requirements.

Spectro 500 Mile Review
I own a Big Dog K9 and had always used Redline Synthetics but had problems getting it into nuetral and had a clunk when shifting gears. Now that I'm using the Spectro, those probllems have dissapeared! Smooth shifting, cooler running, and less transmission noise now. I think I'll be using this product for now on!

Only the Best
Need a tranny oil that out performs? Last longer? Runs Quieter? Runs cooler? Here it is. Recommended also by the top American aftermarket tranny maker. Also the purple tint to the oil makes reading the chrome dipstick a snap.

Will Buy Again
Used this Trans fluid for about a year now, It takes away about 85-90 % of the annoying 5th gear whine , And Transmission shifts great also.

Works
07 FXD with 6spd transmission. Shifts are much quieter, smoother and neutral might be a little easier to find. Down shifting still can be heard, but sound has been reduced a lot
