Need some transmission advice

[Fox Body]

I plan to purchase a Lentech AOD in the near future (within the next 2 months), but I need some advice.

Honestly, the trans that I have now (see sig) needs rebuilding. I was very close to getting it done for about $550 (from a place with a good reputation), but couldn't decide: should I rebuild the C4, and while I'm having a little fun with it, save up for the Lentech, and then purchase the Lentech and sell the C4 or just go ahead and get the Lentech and sell the C4 which needs rebuilding (knowing I can't get half as much $$ from it in it's current condition (takes a few seconds to shift into reverse and doesn't shift 1-2-3 HALF as hard as it use to-- now you can't even tell there is a shift kit in there at all-- and it's slowly getting worse, of course).

I kinda just wanna go ahead and buy the Lentech and sell the C4 (I love my C4!!!).

I know it's not a decision that could determine the fate of mankind, but I would still appreciate you guys' advice.
