6l80??
Hey guys couple years late on reply but I just recently just swapped a 6.2L and a 6L80E trans in my 87 suburban and I love this setup good fuel mileage and doing 66 to 68 the rpms r at 1400 so the double overdrive is well worth it lot better than the dinosaur TH400 although they are reliable- Ericsmithchevy
