No Installation Hassles Since Everything in The Kit Is a Direct Bolt-On Part
In this day and age of “bolt-on” parts the term often leaves a lot to be desired. However, as long as you’re fitting a small block or big block Chevy “classic” transmission to a 6-bolt Gen III LS V8 (which includes 1997-2007 LS1, LS3, LS6, and LS7; 2005-2009 LS2; and Vortec truck engines including the 4.8/5.3/6.0 under RPO codes L33, L59, LM4, LM7, LQ4, LQ9, and LR4) this is truly a bolt-on LS to TH350 adapter conversion solution. Besides the popular TH350 3-speed automatic and classic Powerglide 2-speed, this conversion kit will also work with GM’s non-LS 4-speed overdrive transmissions like the 200-4R, 700-R4, and 4L60.
Note that this is not a direct LS to TH400 adapter kit. While the popular Turbo 400 isn’t supported natively due to its larger 11.50” converter bolt pattern, if you wish to use a TH400 behind your LS you can simply swap your TH400 converter for a and everything will bolt right up then. The modern 4L80E uses the same 11.50” bolt pattern, but is not compatible with this kit, nor will this kit fit extended length crankshafts, such as early 6.0L applications, or 8-bolt crank Gen IV LS engines such as the LSA. If you’re looking to save money and reuse a classic GM small block or big block automatic transmission behind your Gen III LS swap, this easy to use flexplate adapter kit is what you need.
