Flywheel fitment issue on a new Optimizer engine.

[Goose57]

Hi all finally got my new Optimizer set in my truck. I went ahead and bolted the rebuilt 4L80E trans to it and set it in all by myself. I didn’t install torque converter bolts before I set the motor in didn’t want to get under it while it was on the hoist. When I got under the truck to install the torque converter bolts there was a 1/4” gap between the original flex plate /flywheel and the converter. I don’t think I installed the flywheel backwards. There were witnesses marks on the flywheel so you could tell which way it was installed. Do I need to get a spacer for the flywheel since it’s a new Optimizer motor? Any body ever had this issue with a new Optimizer motor? Thanks

The weights on the flywheel should be on the motor side, verify it... You should not have that much gap me thinks...

I checked it looks ok? Just worried about the gap between the flex plate and the converter. All the ones I ever did the gap wasn’t that big. I am going to call the transmission shop.

Verify as Twisted Steel Performance mentioned, then...

Months isn't going to work for me. I need years or decades. I have several feet of Tygon that I can use if needed at some point, as long as it doesn't get brittle after sitting on the shelf for long periods of time. I think the loop would still get hot with heat soak from the engine at...

The converter can move back and forth some. Is it bound up where it won't move? Possible there is a bearing for a MT left in the crankshaft?
