this happened second time today since i owned the car

first time happened about 2 months ago

now today

i belive it is only when i throttle down during transmission shift

i step on gas to pass a car . during shift up i let go the gas slightly because theres a car in front and at that moment i can hear and feel through the floor like something snapped or popped off
looked around last time didnt see anything

when it shifts with foot on gas theres no problem
only when i very slightly release the gas pedal it does the loud popping. snapping sound

 

Can you replicate it by using "manual" shifting?

 

probably not it doesnt sound like i should replicate it on purpose
sounds like when a hose pops off
but i can feel it trough the floor

 

Based on this cars' history with motor mounts and the fact that it's happening after shifts, I'm leaning towards motor mounts. But that's without knowing anything other than what's here...

 

which mount is the prime suspect? i checked the front one and it looks good no liquid
cant see the rear one though

 

Usually the front one fails and causes the side one to fail right after

 

weird it just happened today as i was turning left and uphill
i keep looking in there but dont see anything suspicious

front mount looks good no liquid leaking or anything
can it be something inside tranamission or transfer case?

 

I had a weird VERY, VERY minute click on slowdown right after I would hit a speedbump, and it would only occur after I hit one speedbump. I also had a weird, as I called it, a two step jolt between shifts, if that makes sense? This should help in engine mount diagnosis:

 

mine is not caused by speed bump
only at full throttle shift
or when i juat very slightly back throttle as the car shifts up
i already replaced all the blown out balljoints so now it doesnt clunk on speedbumps

i also got a rattle in vtec a very annoying rattle which at first sounded like really lose valve clearances
mine is a loud pop or snap not clunk

happened again yesterday as i was merging on the freeway
again inbetween shifts

 

The fact that it's happening between gear shifts under load is really making me think mounts, especially given Hondas are notorious for sh***y mounts...

 

can it be faulty hydraulic mount?
like its not leaking but the fluid valve is leaking and making a pop sound thats why i feel it in my foot area?

 

Honestly, mine weren't leaking hydraulic fluid either... Definitely check out the mounts. How does your trans fluid look? What's the service history on the trans?

 

new redline fluid

i took some stuff apart and put it together and havent heard the noise yet but will have to step

 

I would say check the side and rear motor mount.

 

looked at transmission mount looks ok

how the hell do you even check the mounts on this. they have condoms over them cant tell anything

but I haven't heard the snap since then

 

take the condom off

unbolt the covers and it will reveal the cracked broken mount

 

^^^LMFAO, On the side note Justin the RL has more PITA clip to take off compare to the TL.
