700R4 to 4L60E Swap next week - any pointers?

[68 SuperRam]

I am looking to replace my 700R4 with my new 4L60E – which I just received from Bowler - probably early next week. I will be using the TCI computer controlled unit – and the question that I have – are there any helpful points that anyone can pass along that would assist me in this install. I know the casing is the same size – Bowler already did the pre-programming for me and put it on the dyno – so I know that it should start and run fine. I also purchased the additional harnesses that I would need – TPS sensor and distributor connection (just want the install to go as smooth and hassle free as possible – without having to worry about me or the mechanic shop splicing connections during the initial install). I already have an elect speedo – so that should just plug in – and then just recalibrate it. I also purchased a new cross member from BRP. Any points – please pass along – Thanks FYI – 350 block Superram fuel injected – with HEI.
