So it seems my 4L60E has bit the dust and I'd like to replace it with a mild 4L80E but I'm concerned about the loss of low end power due to the tall first gear. Currently I have 3.42's and 29" tires and it seems this combination isn't very desirable with a 4L80E, my truck will mainly be used for just having fun on the streets and the occasional drag strip run. I will also be taking it on the highway since it'll be my DD till I can pick up something else for a DD, so what gears would y'all recommend? I was thinking probably 3.90's but I'm not certain.

Future mods include a Vinci Trucker cam and a Yank 3200 and wayyyy on down the road probably a turbo.


Or would y'all just recommend that I rebuild my 4L60E?

Thanks in advance fellas
