Wanna tighten my convertor up 2-300 rpm whats the John Deere everyone uses? Also heard amsoil synthetic compressor oil is a good one? This should help lock the convertor up sooner as I’m told Any info be appreciate..

John Deere hygard regular viscosity is what your looking for. Results are mixed on this but give it a try.

Thanks

A lot I know use the 10 Wt Cat hydraulic oil with a little dextron, 1/2 quart or less so you can see it on the dipstick.

100-150 tighter than type f with 303 tractor hydraulic on my set up. Your results may vary.

Thanks fo the input I’m running a castol synthetic..It was just under $5 a quart on sale so figured I’d try it..

I tried the Cat Hyd oil, and my car was all over the place. Went back to regular old Valvoline type F and it went back to being deadly.

Do you have to drain the converter or will hyd oil mix with the trans type F?

I have never tried it but one of our local builders who does allot of high HP transmissions swears by Amsoil synthetic compressor oils,for the ability to handle the high heat but also because it is available in 10,20,30 and 40wt to allow you to fine tune yor converter.
