Hi mate, sorry, I didn't even know you'd even left a message lol. Anything can be done at a cost, not 100% sure why you'd want to though as that transmission will be limited in it's hp capabilities. Having said that, I don't know a hell of a lot about it. Unless it's the 5-Speed "Auto-Stick" from the SRT8 vehicles. Either way, my 2c, your truck is already an auto, upgrading to another auto isn't going to achieve much apart from 1 extra gear. If you are that concerned, maybe beef your stock one up and get a slightly higher (lower numerically) rear gear set. Save yourself time and hassle. Going from auto to manual or manual to auto, that's a swap worth while. Hope that help. Cheers!!
