My buddy has a 1999 Suburban with a possible transmission problem.
When the transmission is in drive a clicking sound can be heard from
the transmission area under the truck. The noise is dependent on the
speed on the engine. The clicking can be heard intermittently, not
all of the time. It disappears when the tranny is placed in neutral
while moving or coasting (basically when the tranny is not under
load). Any suggestions?
Sure it is the tranny? Ours has a "ticking" sound and it could fool you into
thinking it is from the tranny area, but it in fact is the gasket from the
exhaust manifold to the pipe on the passenger side. Need to drop it tomorrow
and put in a new gasket. It's needed it for a few months, but I"m finally
getting around to it. It will be nice to have a quiet truck again! The
gasket is gone enough to feel the puffs of exhaust when you carefully reach
up behind it. It has enough play I guess to tap the metal and make an
Just completed the exhaust flange leak repair. Put a new gasket in the
passenger side and reused the driver side. Neither looked bad, but figured
I'd replace the known noisy side while I had it down. My guess is the pipes
just shifted a bit over 100K miles! Oh well, the boys liked the sound of the
open 5.7L anyway. I remember the first one I heard as a little kid when my
Dad fired it up. They thought I should leave it that way for Mom to drive!!!
She on the other hand about jumped out of her shorts when I fired it up.
All back together and as quiet as the day it was new. Simple $9 fix and some
time with a socket wrench and torch this morning.
Moral to the story: Do yourself a favor and look close before running to a
tranny shop and getting screwed over....
