Subject: DML: V6 CC owners....question for you.
Hey. Anybody else with a 42RE have a short "oop" noise
right when you shift into reverse? This is really
bugging me. Sounds like something binding up. It's a
lot worse when I'm facing downhill and shift to
reverse. Then it's more of a drawn out noise,like a
groan,but still lasting no longer than a second.
I checked for play at the driveshaft,and it seems
alright. Thought the transmission mount was doing
it,but it looks like it was designed to allow
side-to-side movement. I can grab the tailshaft of the
tranny and move it back and forth a little.
I had my wife shift from D to R while I looked
underneath,and there was no unusual movement. But when
I held the driveshaft as she shifted,I felt two
distinct movements,like it engages once,then again.
The driveshaft rotates perhaps an additional 1/4-1/2".
So now I'm thinking pinion damage or something (it's a
3.55). 37,000 miles. Another thing,it does in fact
have the characteristic "woooo" noise at certain
highway speeds. I believe this was an issue dealt with
on the list several years ago?
Sorry for the long post. Is it likely that a bad
pinion or worn diff is causing both sounds? Thanks!
