Noop, The problem happened years ago back in the 80's. Folks were putting 80w in the trannies. They were complaining about them being hard to shift. Come to find out when the tranny fluid weight was converted from Metric to English they were actually supposed to have 75w. Speed that up to the present time they are supposed to have 75w90 GL4. The problem with 85w is it makes the tranny tuff to shift when it get's in the 40's. You can mess up a syncro if you shift it wrong cold. This info has been known for years and people still put the wrong fluid in it.
