So I'm pulling into my driveway, slight bump at the end so I always take it slow, as I tap the gas to inch forward the transmission makes an incredibly loud pop/explosion sound. The car will not go into R D 1 2 or 3, it makes a subtle ticking noise.The fluid level is fine and I've had the transmission flushed twice since I bought it at 160,000mi. The car now has 214,000mi on it and the tranny is original.

I have an amazing mechanic at Nissan who takes great care of me and is going to look at it Monday when he is back at work but was just curious to know if anyone had a clue as to what it could be by reading my simple story....

Thanks

Makes a clicking noise?

Put it in gear and rev it up a little, does the speedo rise? If so, it's most likely an axle.

 

thanks for the quick response pmohr.

i just went outside and cranked the car up, even when the car is in park it makes a quiet humming noise. (never made it before last night)

I dropped it into D and reved the engine to about 3 grand and the speedo did nothing....

 

Does the idle change at all when you put in gear?

 

not at all....

 

Check and see if the axle popped out of the transmission or if one of the axles have snapped

 

Pump or converter could've failed. That's my internet diagnosis, anyway.

Does the humming noise increase as you rev up the engine at all?

 

just got underneath the car.. both axels look fine..

 

not that i noticed. its a pretty consistent whether the engine is reved up or not...

 

Looks like you're in for a tow to a shop, really.

So it just free revs when it's in gear, as if it were in park?

 

exactly....

ive got an amazing mechanic over at a local nissan shop and he takes great care of me off the clock but obviously doesnt work on sunday. thank god i also have a cousin who owns a flat bed company and said hell come grab me monday morning....

 

Try to post back with the diagnosis and cause of failure, should be interesting.

 

i definitely will! and once again i appreciate you taking a couple stabs at my issue.

ill keep ya posted
