I would tell them to remove the auto trans before they ship it, your paying for weight and that way you don't have to dispose of it. How cheap is cheap? RB manual trannies are NOT cheap.

you can get a RB26 transmission cheap and mod that to fit....OR i believe the RB26 transmission bellhousing fits on a cheap Z32 transmission...

Yes it does, don't jack around with modding the 26 transmission to fit. They also weigh north of a billion pounds.

Maybe in the 13th century when the Mongols where around and needed Auto trannies for their siege engines to catapult into the cities that didn't submit to their demands.

just wait and get the manual.

manual rb trannies (the good ones), run for 1200 pre-shipping.

you will only find the motor itself for like 1200, if that. So by the time you do the numbers, you've shipped 2 large items and paid 2400 pre-shipping anyway.

just wait and get the manual.

The only thing was i could pick this up and its tax free and i can check it out before buyingI was thinking if i could get him down to $1000 i might do it but i want to make sure that i can still wire it up with no problems

DOES anyone know if there are any wiring issues? AT TO MT

eBay has a rb25det transmission for 1800 haha hopefully i could find a good deal on one somewhere, or just but another motorset and have a built motor later on

What Kind of power will the AT transmission hold? Is there a Stall Converter available?

Also wonder how it would gear the car?

As a Drag Racer, I just wonder if it could not be used at the track to help the RB build boost and be more consistent?

If your just gonna Throw the AT transmission Away, I would take it to experiment with it.
