T45 In A Late 01-02 Mustang Gt?

[Stewart Rife]

So my tremmec 3650 is going out in my GT at around 125k the cluster gear is rattling all over the place. I found a T45 local for a low price around 90k miles. Now I was wondering being an 02 would that transmission go right in? He said it's already been swapped out from mechanical speedo to electronic since it was in his 99. I know I'll have to get a new shifter at least, but would it bolt right up and have no issues otherwise?
My door panel says my car was an 09/01' sold as 02'

Putting a 1999 T45 into 2002 should bolt right up. The possible problems I see are:

• The number of teeth on the OSS sensor is likely to be different. If so, this will make the speedometer read incorrect which can be corrected in the same manner as a rear end ratio change.
• Assume that the T45 comes with a wiring harness.

Seems possible to me that there are slight wiring/connector differences but I would think the differences can be worked through.
