Hi my daughter has a 2007 3dr hatchback with close to 200k the motor finally wore out ! It has the 1.5 w/automatic tranny front wheel drive.
My question is " I have found a 2016 yaris sedan 4dr that is wrecked on front drivers headlight,fender control arm, same motor same tranny are there any known technical difficulties when swapping a gen 3 motor n tranny into a gen 2 chassis ???? From what I can see so far looks pretty basic ! If anyone has done similar please advseme what to lookout for when doing this I.e. .... Harnes changes, different mount location/measurements accessorie location/placments, tranny/motor lineup ? Etc.. This would be very helpful to know and greatly appreciated so I can get this swap done efficiently.
Thanks in advance for any advice y'all might have for this novice mechanic.
P.s. not my first motor/tranny exchange but is my first front wheel drive !!!
