strange transmission problem..
I completed an engine swap, from v6 to L98, and when I did this I had a new 700R4 built (performance parts used) and I installed it (new torque converter too). For some reason, the fastest I can go is about 70 mph in 4th gear at about 4700 rpms... anyone have any ideas as to what could cause this? I have manually shifted it up to make sure it did shift into 4th. Would not having my TV cable adjusted a certain way cause this? I know the guy who built my 700R4, and he is really good at it, he has been building them longer than I have been alive. I am just lost on this one. Any help is great! thanx!

Re: strange transmission problem..
Are you certain you are shifting through all the gears? Are you going into third and just feeling the torque converter lock up?
