LQ 9 4L80 flexplate
I have bolted up my LQ9 and 4L80 transmission. The flat flexplate is snug against the torque converter and I have a 5/16 " gap between the engine block and the transmission casing. Does anyone know what flexplate to use and or if I need to remove a spacer of sort.GM part numbers would be good. The dealership is clueless. Thanks.

I plan on using this spacer. I have purchased it and I am 99% sure thats all I need. I believe That TCI also make one similar

Re: LQ 9 4L80 flexplate
Hello again. I am missing something. LQ 9 has stock flexplate GM 368 stamped into and a bar code sticker with 531 in red writing on it. On the backside it looks to have a ring about 3/8 " thick attached to it . Six torque bolt wholes six bolts to the crank. Does anyone know if this is the wrong flexplate. Driving me nuts.

If you have a dished flex plate and a stock 4L80E converter, it won't work correctly. |

Re: LQ 9 4L80 flexplate
I missed the LQ9 part originally, was just thinking 6.0. But if you truly have an LQ9, then it will not have the correct flexplate for a 4l80e, they didn't come with them, so you would most likely have the dished one. You need the flat one with the spacer.

Re: LQ 9 4L80 flexplate
My LQ4 has a flat flex plate and no spacer with the 4L80 trans. What is different with the LQ9?

Re: LQ 9 4L80 flexplate
This is what the correct flex plate should look like.
