Re: 32 packard gears clashing when warm

As a side note, I started out using 85W-140W in my 4-spd. Shifted fine when cold, but on a hot day after 4-5 hours of driving I would get minimal gear clash if I shifted a little to fast.

I believe the multi-grade was thinning out to much at the higher temps, and not slowing down the gears between shifts.

For summer driving, I tried a single weight 190 synthetic, which eliminated the problem.http://www.amsoil.com/shop/by-product/gear-lube/severe-gear-sae-190/
