Anyone ever use an RB25 Auto-Trans?

[archaeic_bloke]

So, Sean just posted this thing up on my blog about using an RB25 Automatic Transmission, full story here of course: http://skyline-life.blogspot.com/201...automatic.html

But I'm just wondering, anybody out there using an RB25 Automatic? that thing seems really quite beastly for an automatic?

Has anybody considered swapping one in to a GTR before? what do you figure that would take? and more importantly, how much power do you think that could handle?

Also, I know the automatic transmission was originally invented for drag racing use, because it was so much quicker than shifting at the time, but how do you guys figure it would stack up against a regular 5MT tranny from a GTR? (not the getrag of course)...

heres the video he posted that caught my attention, reminds me of that video called "skyline from hell" if anyones seen that.

I can tell you what abuse I once did to an rb25 auto trans one fun night in Nagoya.

Has a skyline rb25 auto 4 dr. I took it to the river roads in the middle of the night. Went around 90km or something close to that in reverse, slam into drive, drive to 100mph, slam in reverse, drive to 80km or so, slam in park..... By this point it was fine. nothing but burnt rubber. I wanted to grenade this auto trans!!!!! So did the same as above once more... Still fine!...... So I hammed the break and gas at a stand still. I boiled out all the trans fluid from an over heat and after no drip drip and a slight burning smell I decided it was time to rest in peace. I took it up to 80km or so again in reverse and so on (same as above). I blew both tires and hobbled back to the yard to go to sleep. woke up next day and cut the car in half, packed it in a container and shipped it away.

Moral of this story is that I couldnt bust that thing even trying my damn near hardest. It still drove me home just fine!!!!! on flat tires hehe

I have no idea.
The car was actually an R32 RB25DE auto. So not sure if the non turbos use a RB20 auto trans or rb25 trans or if their different. Still tho. I was shocked I couldn't bust something inside at the least.
I tossed truck loads of those auto trans in the trash on my chop trips :S Along with all the non turbo CA18DE's.

They do have their faults. Trans fluid overheating is one as factory oilcooler is not good enough and factory oilcooler is known to clog if not serviced. RB20DET auto can take around 380hp at engine without touching internals + without autotrans oilcooler before it drops a gear. Some say shift kit is needed at 350hp.

Autotrans is made by Jatco (part of Nissan) in Japan -

I noticed Jatco compatible shift kits, manual valve bodies are available in USA, but can make car chirp the rear tyres with shift kit.
