Why does my 2001 Ram 1500 5.2L v8 bang at about 40mph every now and then?

Asked by Mar 18, 2015 at 06:55 PM about the 2001 Dodge Ram 1500 2 Dr SLT Standard Cab SB

Question type: Car Customization

It happened twice. At about 35-40mph, like
when it was shifting from 3rd to 4th, the
truck made a loud bang like something
slammed underneath and jerked it forward a
little, about 2 seconds later, again and then it
was fine. It did it once before a couple
weeks ago. I am getting a tranny flush
tomorrow at the dodge dealer cause I know
it needs it. But I also think the plenum pan
gasket could possibly be blown. I feel like it
is consuming a little oil. I am trying to
remove the air filter housing but there is one
piece connecting at the bottom with a
rubber washer or something between it and
it won't come loose. I am trying to see if I
can see oil pooled up which is for sure sign
of the gasket being blown. It's got 77k miles
on it and is clean as can be. Nice truck and
would love to figure this out. It scares me a
little. Any help would be really appreciated.
Thanks for your time guys

If your leaking trans fluid, then yes, you might have some inconsistent shifts. If your having the fluid replaced tomorrow , have the garage repair the leak first, no sense getting it all apart to find you can't do anything about it IMO.

It's not leaking a drop of fluid. The only thing I noticed was my oil is a tad low which I feel is due to a blown plenum pan gasket

Mine did that. It was the timing chain jumping the cogs on the gear.
