Trans Oil Poll

[BUBBIE]

I plan on being in the Orlando & Sebring area the 3rd week of January & am looking for a place where I can purchase either the spectro heavy duty 6 speed or the redline with shockproof

HOPE THIS IS IN TIME

I went to Red Line Oil: Dealers This should help get product.

I use redline products SHOCKPROOF HVY in tranny I have NO METAL NEVER on magnet!

I wonder if the Spectro importer here has the 6 speed. I used to use Spectro in my old Sporty many moons ago. I have some left from when I did a bulk buy. I now use it in my lawn mower.

Hey glider, my owners manual says to use part no. 99851-05 whitch is 20/50 engine oil according to the amsoil chart. Is this rite? Should I put the 75/140 in the primary and trans?

 

[glider]

Engine oil is for engines, gear oil is for transmissions.The one size fits all doesn't cut it in real life. That part number you posted is the Formula+ from HD and you can use it in the primary, I would use a gear oil because of the differences in the composition between the two in the trans like Spectro platinum, redline shockproof or Mobil 1 75/90 or 75/140 but all gear lubes and in the trans.

Thanks glider. I have amsoil 20/50 in all (3) at this time. I am going to change the trans to 75/140. I am in 4 feet of snow and -20 (fargo nd) so it will be some time before I have the chance to try it. I have a question on the GL rateing for gear lube. They go from GL-1 to GL-5. Is the GL-1 lube the best for the trans or should I go to a higher number? We use GL-4 or 5 in the auto industry.

have used mineral in both my bikes also in big trucks cheaper and never had a problem. main reason is when i retired several yr,s ago had 2 five gallon pails of the stuff settin in the shop

Are you referring to mineral oil or dino oil (regular oil meaning not synthetic) Hardly a good choice in the trans.

 

[jdaws]

Correct me if I am wrong! The higher the GL number the more antiscuffing additives it has. Spetro has an API GL-1 rating. Is this the rating to use for the trans?

 

[glider]

Spectro's GL1 is for the 5 speeds. Their GL5 is for the 6 speeds with the helical gears. The GL numbers refer to the make up of the oil.

Plenty to read here...
