A4 to A3 Swap guys in here!
Any good info or pics perhaps even a write up on this??? I have an 03 Reg Cab Silverado with an LS1 and the truck 4l60e. I want to convert to a TH350. Thanks in advance.

I plan doing a write up for this like I did for the T56 swap when I do my TH400.
AFAIK, you'll need an SFI flexplate with a spacer so you can use an off the shelf TH350/400 converter. You'll need to modify your crossmember. You can get a reluctor ring installed on the tailshaft so you can use a VSS out of a late 80's early 90's OBS truck. All you'll need to do then is change the tooth count in your tune. You'll need a shifter/cable and dip stick. You'll probably need to modify your driveshaft too which will be a good time to upgrade to some 1350 u-joints.
