RECOMMEND THIS PRODUCT:

Good product

June 22, 2016
Nice fit. Worked perfectly together with the starter and all on my 2000 LS1. Just remember to check that the holes line up on your converter. I didn't and had to take everything apart again and redrill it. Very easy task, though, just use the old flexplate as template and drill three new 1/2" holes. I am not 100 percent sure my converter is stock (1969 BOP th350), therefore I give this product a full five star review.
Pros:
  • Fit
  • Price

What is the torque converter bolt circle diameter on this flexplate? I have a 2004 Chevy 5.3L I want to connect to a TH400 transmission. The torque converter I have is aftermarket with a 10.75 inch bolt circle diameter. I just want to verify this is the correct flexplate for my application.

Yes this flex plate will fit your TH400 torque converter with 10.75" bolt circle. GM only used two bolt patterns for the TH350 and TH400 transmissions and this flex plate has both patterns.

Which converter bolts? Just got one of these flexplates. The bolt holes for the converter are quite large. Which type of bolt would you recommend? I assume the bolts should fit tightly in the holes for optimal strength.

Standard torque converter bolts such as 1012307303 can be used with this flex plate as long as your converter has a tab with a hole through it. If your converter is threaded you will need to use the correct thread size and length of bolt for it. You can use the original torque converter bolts if you have them.

LS flexplate number 57534610 is an improved stock dimensioned 168 tooth flexplate which will work with a stock starter for the 168 tooth flexplate.

Sorry for the confusion, this will only work with the th350 and th400 with adapter part #57518346. It will work with the older 700R4 and 4160E transmissions but will not work with the LS series 700R4 and 4160E transmissions.
