I installed the corvette servo and .5 boost valve but the 1-2 shift still feels soft. Did I do something wrong?? Funny thing is the 2-3 shift is firmer tho......

 

did you reset the TV cable?

 

yea...reset the cable still the same....

 

you need to change the 1-2 accumlator piston spring. hopefully some one will chime and let you know what color spring to use.

 

Is that the spring inside the 1-2 apply servo that I had to change from the stock servo to the new servo. In the instructions it says to install a blue spring along with the stock white spring but the kit I got had no new springs. I instaled the stock spring with the stock snap ring even tho it says to discard the snap ring. Any more help on where to get this spring???
Thanks!!

 

the 1-2 accumlator piston spring located by the valve body not the servo. it's probably broken.(that's very common) if it's not it still should be changed. the stock one sucks.


here's a pic.........

 

Get a white or plain "flat" wound spring in a 1990 & up unit (not the orange tapered) and install it with washers underneath the piston, so that the spring comes out of the hole by about 1/16 -1/8 of an inch, a slight preload is all you need. This will firm up the 1-2 WOT shift.

 

Probuilt what spring are you refering to the one in the servo was already white or the 1-2 accumulator spring mystikkal_69 is talking about?? Where can I get these springs and where is the accumulator spring located valve body? Do you have anymore pics?

 

It is the spring pushing against the piston in the aluminum housing (2nd gear accumulator) held down with 3 bolts, next to the valve body.
