[chris989]

Hello,

I am swapping in a 4l80 to replace the 400 turbo. I need a 4l80 dust cover for a 5.7 motor.

I have a 7.4 cover and it will work with big gaps. (gm# 15639045)
The 400 cover is (gm#1552212) it will not work at all.

I have be cruising the net and can not be sure which i need, At GMpartsgiant there are multiple ones that they say will fit but.
