Which one has better ratios or are they the same? I am thinking about converting my 02 gt to a T45 if it's worth it.

 

Why would you go from on POS transmission to a worst(IMO) transmission?

The gear ratios are practically the same except the 3650 has a taller 5th gear so you can run a more agressive gear while keeping the revs down more during regular driving. There is no point of going to a T45 especially if you think it's going to make your car faster. Everything from Tremec that people use in our cars have basically the same gearing except their overdrive gear.

 

neither, and especially not a t-45.. I think mine is starting to give up on me..[:@][:@]

 

lol usually this swap goes the other way around. Im going with a 3650 reallly soon. the t45 is a pos. I had one built up and everything and the POS still broke

 

I've got a tko600 in my fox body, but i don't have the money to buy another one. There's a company down the road from my place of employment selling BRAND NEW T45's for $700, so i figured if they were worth a damn, i'd buy 1 @ that price.

 

no keep 3650.... or ill trade you my t45 for your 3650.... lol
