NEED HELP early 4l60e to 08 4l60e

i have an early 4l60e from 93 bolted to an 06 LQ9 in my 93 sierra step-side. i am thinking of swapping for a rebuilt 08 4l60e that is available here in town, i want to know if i will run into any problems, right now i have a modified flex plate to fit an precision industries TC for an early 4l60e, will i need to change my TC and will i run into any other problems? id really appreciate some help if anyone out there is familiar with this conversion. Thank you :rolly:

Does the 93 input shaft have the pilot on the end?
