alright when im in first gear and hit above 3 grand sometimes my truck will make a high pitched wining noise. it drives fine during and the noise and stops as soon as i hit second but its just weird and it sounds like its coming from the tranny.

 

Hmm... strange. Sounds like my truck, but i determined that it was coming from the speakers, lol. And it only happens in 1st after 3k?

 

How are your U joints?

 

u need to take me for a ride so i can hear it...

 

it only happens after 3 grand in first its weird and i dont see how it could be u joints

 

my friends dad thinks it is like harmonics like something vibrates to make that noise idk wut else it could be i guess i have to wait till it gets worse so we can pin point it and now it happens only at a certain rpm and on some bumps and only when its warm
