Im sure this has been covered before but after an hour of search im not finding the answer i need. Are all neo transmissions pull type clutches? Im looking at buying one and the guy is saying it is a push type neo transmission. Is this possible? Also are the input shafts the same between a neo and a regular rb25 transmission. Im going to use my exedy hyper single out of my rb20det on my new project and i need to make sure it will work for all rb25 transmissions(neo or regular) as long as it is a push type clutch.

To my knowledge they are all pull UNLESS he did the modification to make it push which is posted on here. It's quite simple and cheap (in the long run). Ask him for pics

It was a miss communication on the transmission it is a pull type. Do you know if the spline on the input shaft is the same as a regular rb25 and if so what makes the neo so much better than the regular transmission? If i tear up a neo transmission would i still be able to swap the gears and internals from a z32 into it?

almost 100% positive the input shaft is the same. and why swap internals with that of a z32 transmission? just swap bellhousings.

Mainly because i dont want to have shifter and driveshaft issues. Are neo transmission any stronger?

negative ghostrider.....the transmission even though its from the NEO, its not any stronger than that of a normal RB25 transmission...now the Z32 transmission is stronger, not because of the internals being stronger but because the overall transmission case is shorter ...shorter means less flexing within the rotating assembly

there is no difference between the two in any way shape or form...both of them are the exact same transmission...
