I have been searching all over the forum and found some opinions and facts. only problem is their all from 2008.

What is the best fluids for my 5 speed shep trans and shep transfercase. and rear diff .. please no negative comments i know there is a sh** load of threads on this.
I just want to know what bottom line people are using.

Some say redline made their trans notchy, some say amsoil is better , some say oem all the way.

Thanks

 

Get ahold of shep and ask them.

 

they say straight mt-90 Redline. but have seen couple forums to go with amsoil or oem. so just want to see whats everybody runing

 

I have a TRE trans, and have Amsoil's 75w90 trans fluid to shift a bit smoother than the redline. TRE says amsoil or redline is fine. If shep built the trans, I would run what shep recommends.

 

I ran Lucas 75w90 and is fine in my shep
