I have the "diesel knock" sound in first gear when accelerating and have been told it's due to pitting on the output shaft (common on the 2.8L).
Don't want to spend the $$$$ on a new/rebuilt tranny or a new output shaft.
Just want to quiet it doen as much as possible.

also, try counterbalancing the containment module with a crossdrilled transmission tubalator.

The extra Friction Modifers and shock load additives that GL-5 has over the recommended GL-4 MTF might help quiet it and bunch and actually reduce friction. As long as the syncros still catch nicely, it is well worth a try. Let us know if it works. I'd blend it according to your climatic needs.
btw- WalMart's ST Synth GL-5 140 is like $7 in case you want to experiment, even drain half your fluid and mix in this as a test for visc and partial additive boost. You could even do that with dino GL-5. otoh, using Mobil 1 is not expensive ($11) and will take the additive levels fully up to GL-5 spec. Nothing worng with DuraBlend either. Some places sell Valvoline SynPower Gear oil too.

I think I should look for a new one. How can a professional not do such an important procedure? To tell you the truth I don't think he knows anything about it.
