First ls swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

If that Tahoe has a 6speed auto, the trans is a little bit larger but you should still be able to make the stock xmember work. The trans crossmember on most of the old trucks is just a bar with 4 bolts holding it it. All you really need to do is set the engine combo in, then slide the crossmember back as needed and drill a few new holes.

The trans mount might be a tad different as well (the 4l80e has a different mount than the 60e/th350/700r4, and I'm not sure what style the 6speeds use).
