hey speed experts I got a good question for yall.  I have a 97' Camaro with a LT1 and my problem is i used to have a 1 piece 4L60e but recently installed a 2 piece 4L60e with a removable bell housing i had 2 make a few mods to make it fit.  My question is what all do you have 2 do to make the 2 piece 4L60e work in the LT1???????  It worked for a about 100 miles but after that started missing second gear and not upshifting at all sometimes.  Its also making a whining sound.  I know the 2 piece is for the LS1 but im trying 2 make it work.   anybody out there
