ive been thinking/ worring about my auto tranny in my vert.. had me thinking about somethings... also somethings about getting more power... yeah yeah yeah i know auto's suck and im not gonna get that much power........

but anyways..... can u put a automatic transmission that came out of an FD in to an n/a FC? ...... ive heard that they are alittle more beefed up then the ones that are in the FC..... thanks guys ... any advice would be great ... except for the auto to manual conversion....

Does your auto not work? i had 180k miles on my auto and it worked fine.now its sitting in my garage,if you need one ill give it too you dirt cheap.
About the fd trans it's not a bolt in.

well mines works and all .. just that the shifting sucks on it .. i only have 98k miles on mine right now,.... im just wondering... .. so it is possible though? (fd tranny into fc ?) and do they make shifts kits for the fc transmissions?..

i do think that the FD auto tranny will bolt up to the back of an FC i mean cmon its the smae rear iron i doubt mazda is going to change it just because of the year neways babygurl i think only problem you have is the driveshaft im not shure if there exact same lengths

well if there is a ppf on the auto's from a FD like in manuals. if it does it might not work. anybody have any pics of the 2 side by side?

try using an auto tranny from a tII, they work great. I had a ride in one(jspec fc) with aprox. 390 hp and it shifts great and fukin drives very damn good.

Isn't the FD auto trans some piece of junk from the MPV minivan?

Not to mention they're electronicly controlled, so you'd have to swap out the AT computer's and figure out that wiring mess and so forth.

babygurl im sorry but they dont make a shift kit fot the auto fc's.

If you are really worried about reliability, learn to drive stick (if you don't know how to, that is) and drop in a manual trans. It will save you a lot of headache, and make driving your vert a much more rewarding experience. The auto 'vert is the slowest seven ever made. I understand that speed may not be a deciding factor for you, but for reliability's sake, lose the slushbox.

MARTIN

for the TII auto, its basically just plug and play... Except you can play alot harder.

Yeah, I was refering to the FD tranny wiring/computer being different.

the FD tranny is not stronger. Most drag racers swap their FD stuff for a FC tranny and rear end.

sorry to bring this all back guys.. but i have a question so if i was to get a tII tranny .. in my auto.. there would be a pretty good difference? and can u switch them out on a vert?

MARTIN

What mods do you have? If you go tII you need the whole drivetrain. flywheel,clutch, PP, driveshaft and rear end...

rx7babygurl85

well i havent done much so far.. alls ive done is remove cats.. but i still have the precat on there, emissions removel and doing electical ports.... so i would have to do a manual swap to put that tranny on?

MARTIN

yea

Whats wrong with the automatic?
Flush the ATF with synthetic, and drive it until it breaks.

This is an excellent transmission(family) that is used in many vehicles(Nissan/Mazda/Subaru) over the years.

my transmission just shifts really hard it revs up to almost 3800 rpms and then it shifts and pulls back when it does shift..but as for the my transmission is good .. but ive been thinking and kinda was told that if i get a better tranismission id have alittle bit more power..then i heard that the fd automatic transmission was alittle beefed up.. so i thought i could maybe go that way... a bit pricey ... but i dunno... im wanting to get more power and all ... but i dont want to do the manual swap (cant drive a stick and ive tryed just dont like it) i know that would be the best way to get power and all .. but i dont like the manual.. so the tII would be useless cause id have to do that swap to manual ... .. what really can i do.. ive had an automatic bmw .. and it was betterin go then my 7..

N4A-EL Correction Spring ??? what would this do?

SK® N4AEL

929 & RX7
1988-90
Corrects/Prevents/Reduces:
1-2 slide; spin up 2-3; 3-2 cut loose; mushy 4th;
soft lockup; soft shifts.

is that a shift kit? (its under import shift kits)

please be a bit patient with me ... im SO new to pretty much all of this.. thanks guys...

rx7babygurl85

hhmmmmm... ?

Most shift kits are just corrections for sloppy shifting OEM transmissions.

What you need to do is see if the tranny can be upgraded with the GUTS from the FD or any vehicle using the same transmission family. Find a core from the FD, a core from the FC, and locate a shop willing to do some THINKING.
A competent/reputable shop will know how closely related the transmissions are.
Sometimes a stronger tranny just has a couple more parts to it(like extra clutches, better ATF pump, little more ATF PSI.......).

rx7babygurl85

atf psi? atf pump? GRRRRR!!! why does everything seem to get more and more difficult... im getting so lost...
