so I went to a local Indy shop today who is a dealer in the Spectro line of oils. I said I wanted to try the spectro 6 speed formula. He sold me one quart of the fluid and said that is all I need, and It is sold so you only need 1 bottle, He said thats all he uses when he does fluid swaps at the shop. Now I thought all the 6 speeds needed 38oz, which is 1.3 quarts??? do I need to buy a second bottle? is the Indy wrong? He does alot of bikes....

 

This is one of the reasons I wish we would go to the metric system in this country you need only .95 quarts. You sound like your confusing the trans with the primary. When you change the trans fluid dont just dump the whole quart in there use the dip stick to check, that fluid is great btw I have been using this for awhile now.

 

my manual says 32 fl ounces for tranny for a 10 ultra

 

Hmmmm, you never said what kind of bike your have..
Assuming that you have a new-er touring bike as this thread is in the touring section. The primary does require 38 oz.
The transmission requires 32 oz.

I like spectro. HD 75/140 Platnium 6 speed.

 

good stuff, using it in my 09 classic

 

The primary takes 38 oz. The tranny takes 32oz.

 

Lol sorry guys my bike is a 2009 FLHT-P with the 103" and 6 speed, This is my first HD, so i am not used to having to change 3 fluids LOL, Im used to my metric bikes LOL. Your right i got the Primary and Tranny mixed up

 

That's what I use...and I like it ! ! !

 

Looks like strawberry syrup, smells like **** and shifts like butter.

 

The only thing that I didn't like about my Road King was the way it shifted, until I changed to Spectro. It is a great product.
