Guys , im wanting to change my t350 box for a 700 auto..
what bits do i need? do things like flexplate, convertor etc need to be changed. Ive read sumwhere the crossmember can be slid back and use one set of the exsisting holes and drill 2 more to fit.
any advice would be apeciatted.

in my chevelle i slid the cross member back drill two holes and had to use a skinnier cross member mount . t350 and 700 use the same slip yoke thats a bonus but you need to shorten your tail shaft . my speedo cable fitted as well . i brought a converter lock up box controler from b&m it works grait , i have a 3000rpm stall and i can over ride it with the diel . the main thing is the tv cable if thats not rite your box will not get anough oil and over heat and burn the cluches out . you can get a kit that always has oil presure so you want burn your box i think thay were artcarr or transco i love my artcarr shifter it the bestshifter i have ever had . i hope thats a bit of help

thanx jason, that defintly helps ...

starter and flex plate - will they fit?
trans tunnell - any mods?
do they sell specific 4 speed shifters for these autos?
do i need a lockup box as jason describes?

dosnt sound like its too much hassle.

On a Camaro subframe, you can't slid the crossmember back. It's location is recessed in the rails. Aftermarket crossmembers for 4L60/TH700 should be out there.
