any whine i heard was from my gears, and it's pretty much a light humm. Sounds like if you know its comming from underneath you in ur tranny then it could just be old seals, bearings, steels, or unseated clutches. Doesn't sound like a big problem to me, after 11 years stuff begins to get unseated/imbalanced. A good way to check if it's a bad sound is to start the car and let it warm up, then take a long funnel and stick it in the dip stick line then put your ear to it. Then put the tranny in drive and set the parking brake and listen to it again, anything thats happening constantly like a soft humming is fine, if the sound is galloping then somethings off. If you have any queations PM me, I've gotten fairly close to the 4R70W lately, lol.CobraRed, before you replaced your TC did your tranny have a whine/hum to it when the car warmed while driving? Mine does and its been a mystery...My friend has it in his 96 GT Vert as well but his isnt as loud as mine...The hum/whine doesnt effect performance on the car just annoying lol...
symptoms...going down hill you can hear it get lil louder, going up hill u barely hear it at all...driving on the highway medium...Just wondering if you had the same problem?

Are you feeling vibrations?
The reason i rebuilt the tranny (+ some goodies) was cuz i was having torque converter clutch problems which caused shuddering in low rpm's around 35-45mph. Also the 1-2 shift would want wait till 200rpm's past redline at WOT and just generally took too long in a normal shifting which was caused from a poor/broken 1-2 accumulator spring.
No there isnt any vibrations at all, just a whine/hum while driving the car...If i rev it up in Neutral you dont hear it at all...Its just underload...like i said before, it doesnt effect shifting or anything of that nature..Just irritating when you drive a long period of time...Basically all i want to hear is just exhaust not that plus exhaust...lol
Ahhh you know what the whine sound like...a very faint supercharger from an 03 ahaha...thats the way i can describe..but its not loud at all..only audible inside the car while driving it...

Some of the 4R70W valve bodies are noisy. The sound can be described as a whine.
