hey guys,

im sure this has been brought up many of times but i cannot for the life of me find where to search the topics.. :|

im curious as to what the auto gearbox's are like and what my options are with a 25det.

i have a series 2 r33 gts25t and my manual box is in need of a rebuild so i have decided i want to convert to an auto box as i am setting the car up for drag.

i plan on seeting it up with a highstall, manual valve body an quick shift.

any help would be greatly appreciated. preferably from someone with experience using an auto box or an after market auto box.. so i can get a good idea of which direction to take..

thank you in advance

c4: old school Ford 3 speed can handeling big power but will need trans tunnel massaging.

2 speed powerglide: really old chev box can handle stupid huge power but not ogre. ull see used in a skyline/street application.

mv autos in Adelaide is the best place to use apparently but i have no personal experience with the

RE4R01A is a 4 speed with overdrive not 3 speed. . .MV automatics in south aus is your best bet for upgraded trans components inc valve bodies etc. . .stronger RE4R01A trans can be found in Y31 cedrics/cimas but need a change of bell houses from VG to RB

im thinking the RE4r03a is goin to be the pic from the research ive done so far..

basing my decision on the fact it will be the easiest to install, price, and availability of parts to upgrade as i increase the power figuers..

an yes this box is a 4 speed. 3 gears with an over drive as fourth.. which in drag racing terms says its a 3 speed as overdrive is just for cruising..

nikk, ill add you as a friend.. im interested to know how you go. will also keep you informed of how my set up goes :)

does anyone know what is required on the bell housing side of things to fit a RE4r03a to a rb25det?

an can some one who has actually had some work done with either of these boxs on a 25 please enlighten me with a little information on what prices you have paid to have what done..

my plan is to set up with a full manaul valve body, quickshift, and highstall.. an power figure being around the 400 rwkw.. and application being drag..

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
