Trannie and TQ questions

[stroke99]

Well my stock converter threw in the towel and now i have to figure out where to go from here...
I have a couple mods fuel pressure mod, wastegate mod, and cut factory air box to pull from the fender...then the stuff in my sig block

Now i need some inputs about companies for the 4R100 as well as converters

I've talked to BTS but there wanting $4200 for their trannie/TC thats about a grand more then i can spend.

Oh and i use the truck from my DD, the occasional dodge/bowtie chew toy, as well as towing my car 100 miles to the track and back....

thanks
