Model number for transmission

I have a 2003 Venture that I just got and was wondering if anyone knows what model of transmission would be in this van? I believe it is a 4T65E, but I'm not 100% sure on that. The reason I need to know this is I want to order a shift kit for it to firm up the shifts a bit and wade my way around potential problems, so I need the model so I can order the right kit. Thanks guys!

My 2000 model year is a 4T65E so I assume yours is also.
