I used the sealent but then I ordered the gaskets later. The gasket is good because it'll reduce some tranny noise if you put in the between the handle and the shifter.
Agreed - same here, if I had it to do over again, I'd use the gasket solution. Less noise, less chance of getting RTV in the trannie, easy to remove, etc...
If the gasket will make it quieter i'm getting them cause with mine in 5th running about 70 with flowmaster cutoff in front of the rear axle and no cats its gets annoying listening to the tranny.
