Need help with correct gear ratio/tire size for a 3 speed auto

I used to have 3.07 gears with 30 inch tires. I now have 32 inch tires and I have upgraded my gears to 3.73 with the stock 32rh 3 speed auto but I have maxed out the 3 speed auto at around 60 mph. Dealership and transmission place told me that I maxed out the 3 speed and now need the 4 speed. My question is what is the correct gear ratio for 32 inch tires and a 3 speed auto.Closer to stock specs. Not looking at changing out the tranny.

3.07 gears with the 32 inch tires did not max out the 3 speed auto but didnt have no power going to the rear wheels and thats why i changed them to 3.73 but now maxed out the 3 speed. Not sure where to go from here and would like some opinions. Thanks

Since this is the newbie check-in area, you may not get the answers you are looking for. I suggest you check here TJ Jeep Wrangler Forum - Jeep Wrangler Forum and post your questions there if you can't find the answers.

In the mean time, I just want to say . . .
