last week i installed the vette servos. at wot i hear a whistle or squeek when it shifts from 1 to 2 not sure if its the belts or transmission. also if i'm not moving(parked) and i shift from 1 to 2 or 3 to 2 the transmission makes a whistle. do you guys know what this is? i have a 2006 chevy crew cab 1500 2wd intake, exahust, tune by wheatley 91 oct 60% tq out, and firmer shifts. also i added the vette servos after the tune and the line pressure in the transmission is close to stock i think.


thanks for the help.

 

the squeak from 1st to 2nd is your serpentine belt.
don't know about the other problem your experiencing though.

 

are you chirping the tires when you shift?

 

no the tires wont chirp but the shifts are firm from 1st to 2nd and 2nd to 3rd at 1/2 throttle. just ordered another vette servo and a 4th gear billet servo today. i'm going to install the vette servo that i have in my truck to my blazer and install the new ones in my truck.
