I found a post and alot more like it saying about the Shift improver kit from J Body Performance. If i was to get this and install it myself what all is involed and how long would it take?

summit nor jegs has that kit... i just tried searchin for them

You might have to try a locally owened transmission shop, one that carries TranStar Industries parts. I haven't worked with the JBP kit, but from what I hear it is just an overpriced version of the TransGo Shift Kit (see about halfway down the page, SK®125)

As for installing these kits, you have to remove the bottm pan and the side valve body cover. You don't have to remove the tanny to do this , but the car must be raised up and supported. The bottom pan is the same as doing a fluid and filter change. The side VB cover is a little more difficult. while the car is raised and su[pported remove the left fron tire and the plastic inner liner. Remove the drivers side trans mount (with the engine and tranny supprted), lower the engine tranny so that the passenger side mounts support them. You can now remove the cover and get to the valve body. Any time you work on the valve body, it is imperative that you keep it clean as possible, some of the valves in there will stick with just a piece of lint. There will be some drilling of the valve body and separator pltes involved. You will also need some feeler gauges and a micrometer(and/or dial gauge) needed to do some measurements. during reassembly, you need to make sure all parts are as clean as possible to prevent any problems. The instructions will tell you all the detailed information on how to do the mods necessary.

well from the sounds of that i'll let a shop do it lol

Yeah, for our cars, it's not for the faint of heart. For most RWD applications, it's pretty easy, because the valve body is behind the pan.
