Qst - Velvet drive Transmission help appreciated.

I'm changing oil today and going thru all my manuals can't find what to do on my transmission. I have the Borg Warner Velvet drive on a Perkins 4-236. The dipstick shows the correct level and the fluid is clean but I don't find any reference as to what to put in it, how often and if there is a filter somewhere that needs to be changed.

Any help is appreciated. Don't ever want to replace one.

I got one too.

Use ATF Dextron (sp)
Change once a season or as needed
There is no filter that I know of.
It should take about 1.25 qrts.
Check your coolers as well.

Look under the shop manuals thread. It shouldbe in there.

Mr. Wheels should jump in here any moment.

It's kind of like tearing up $100 bills while standing in a cold shower.

Aloha Dave,
This is all paraphrased straight out of my Velvet Drive Service Manual,
"Check the oil after the transmission has been running and is at operating termperature. Shut down the engine with the shift lever in neutral and immediately check the oil level.
Use Dexron Type F (ATF) or any hydraulic fluid which meets the C-3 oil specification.
Change oil if operating temperatures have exceeded 190 deg.. Change once every 1000 hours or annually.
If your engine never reaches 3000 rpm you can use a high quality 30 weight oil but never mix different oils or fluid in the trans."
Hope this helps.

I don't need to, you two have done great.
Although, running Amsoil ATF is a great idea if you can get hold of it. You won't have to change it again for a very long time and it reduces the heat dramaticly. Just keep a regular inspection to ensure you have no water in the oil.
No I don't sell it or represent it. hmmmm......maybe I should :-)

For God so loved the world..........He didn't send a committee.
