I went down to the trans shop today where they are beefing up my trans. Put a caliper on 3rd gear of the 2001 AE LSD trans so that we can put fact to this rumor that 00-01 trans have a thicker third gear than 95-99s. 3rd gear was 14.31mm thick.

Anyone have 95-99 trans apart right now that they can measure 3rd gear in? I will do it myself in a couple weeks whenever I take the blown trans out but if someone has it apart right now we could know for sure right away.

BTW they described the gears in the maxima trans as "dainty... like honda gears." He said he would HIGHLY advise shifting easy into 3rd if I want this trans to last with the type of power I am putting down. He showed me a stock DSM 3rd gear to compare it to, and the DSM 3rd gear is probably a good 3-4mm thicker (I will measure next time I'm down there), also the teeth on our 3rd, 4th, and 5th gears are very fine which is not good for powerhandling either.

I learned a ton of stuff down there today, he let me do some magnafluxing showed me some gear detailing, showed me custom CNC spider gear sets they do, bronze wear pads they put on modified evo 8 shift forks for DSM trans, all sorts of cool stuff.

By the way we have double synchros on 1st and 2nd gear which is nice. They install double synchros in their $3000 DSM race trans' because they don't come with them.

He said it's up to me if I want to get the gears cryo'd. Said cryo treating is more for wear resistance than actual strength, he said strength might be increased by like 10% or so, but in the wear resistance is where you really see the benefits.

 

i measured the 3rd gear out of one of my 3rd gen 5spds (same as 4th gen)

i used a tape measue and got 9/16 which converts to 14.2875 so its proboly the same size HOPEFULLY for your sake its made of better matireal

 

So it seems settled then, the 00-01 looks like it is no thicker and I'm sure no stronger than the 95-99. I always doubted they would keep everything the same in the trans but just decide randomly to put a thicker third gear in it for no reason. I'm sure it's made of no different material than the rest of the gears are, that too wouldn't make any sense.

 

Neal, I think Nissan uses the same f*cking thing in all of their cars. I put 1-2-3 Altima gears (the 2.4L 4-banger!) in my 1995 Tranny and 3rd gear is the SAME thickness, just geared a little more agressively.

 

be thankful you don't have the 89-94 trannies. they don't even hold up to the stock 160 hp and 180 ft. lb. of torque that the VG puts out.

 

Maxima trannies seem to suck in general, they put all in the engine and came up with the transmission as an afterthought.

 

haha.. in a way i agree... have you filed a lawsuit with Borg Warner yet?.... lol

im running 11 psi through my vg right now and my stock 173000 mile tranny seems to be takin it ok. we shall see at the drag strip friday night if it can hold up there.

supposidly all of the non lsd 5 speeds have the same gears... 89 and up even 95 and up.. so this is what iv heard.

 

What is the trans code on the VG trans?

 

Mtcookson???? you know this

 

the VE trans code is RS5F50A/V, just like the 4th gens, so I'm guessing the VG is the same. Also all the gears are the same ratios except final gear which is 3.266 on the VE and 3.428 on the VQ.

 

RS5F50A (should be the same for any non-vlsd Maxima except for the 6-speeds. the same code is used on various other 5-speed fwd Nissans like the Altima and such)

RS5F50V for the vlsd 5-speeds. used in the 92-94 VE and the code should be the same for the 4th gens with vlsd. the bell housing is different between the VG/VE and VQ though, which always makes me wonder why the tranny codes are the same. its like saying the big mac and double quarter pounder are the same because they have two beef[like] patties.

speaking of using the same code, they even used the same code on the awd 5-speed available in the Nissan Axxess (which got me thinking of awd swap ideas. )

Here's a good site I found with lots of tranny codes and gear ratios: http://vibratesoftware.com/html_help...nsmissions.htm

which then got me thinking..... hmmmm

 

i have compared the gears from my lsd trans to an non lsd trans out of an 87 and the gears are the same "size" but different ratios the only diference is the final drive/differential

im pretty sure all the gears are interchangeablefrom between all the RS5F50A/V trans

 

What about the Altima 5speed(2k2+) It has a differ tranny number.

 

OT: Neal, what exactly are you beefing up on your trans?

 

rob @ nrh says he uses pathfinder gears for his trannys

 

Anybody want to sell there 2001 AE LSD tranny?

 

which would be Z32 gears (which are also supposed to be the same as skyline gears). the Z32 trannies have been proven to handle 600 hp.

 

The 50 year old powerglide is still

 

Would Z32 gears fit in a maxima 5-speed? If the code is RSF50A or RSF50V they should fit (i.e the main shafts) in the maxima tranny.

 

Someone please find out what the deal is with these gears, i got a blown 5sp on the the floor in my garage and would like to do something with it.

 

The Z32 does not use the RS5F50A/V. It says the Z31 87-89 manual turbos, Z32 turbos, trucks, pathfinders all use the FS5R30A. Some internals might be swappable, but we will not know without looking at them. If anything it would just be the gears. The shafts and final drive go the opposite way inside the transmission IIRC.

 

I just mentioned the Z32 because someone said some uses Pathfinder gears for their setup (and Pathfinder gears are the same as Z32 gears which are supposed to be very strong.)

 

It would definitely make for some stronger trannies for us if they were swappable. Does anyone know if they are swappable with the sentra gearbox the RS5F70A?
