    601080K is rated 1.0 out of 5 by 1.
    Rated 1 out of 5 by from Did not come close to fitting I bought this to use on a 2000 5.3 LS with a th350 transmission. The flexplate will work but the spacer and bolts will not work at all. The spacer will not allow the converter to slide up to the flexplate. There is about 1/8th of an inch gap between the torque converter holes and the flexplate. I tried this one. Then the same adapter made by Cheverolet performance. Both failed. Save your money and buy the plate seperately then the ring style hub extension.

    I'm trying to bolt a 1998 non ls 460e trans to a 1999 5.3 Silverado cause I screwed up bought the wrong used trans would this fix my problem due to the removable bellhousings on these trans are different lengths Wich convert/belhousing would I use

    Asked by: Oldkentucky
    correct that would fix the issue you are having with the bell, but you need to also use a normal SBC torque converter too.

    Will this Flexplate work with a 2004 5.3L LS engine to a 1994 4L80E transmission?

    Asked by: Bobby69x3
    No, it will not work, here is a footnote from the crank spacer information; Will NOT Fit: 4L80E Transmission 1999-00 6.0L with long snout crank (use TCI 890-399753 or GM 809-19260102 flexplate only, along with original bolts)

    I have a 2006 6.0 engine, my engine had the spacer on the crank. I’m swapping a th400 in now so this is the correct style right? Also what’s the bolt pattern for the TC?

    Asked by: Nickf813
    Yes, this is the correct style flexplate and this is the converter bolt pattern; Dual Converter Bolt Pattern: Stock (11-1/16" or 281 mm) TH350/400/700R4/4L60 (10-3/4" or 273 mm)
