I have both a 91 and a 96 Maxima. Both are 5MT.

Now, due to very unfortunate series of events the 5MT in my 91 was trashed. (almost beyond repair, 3 and 5 need new gears, all the syncros, etc.)

SO, I also have an EXTRA 5MT for my 96. As im looking at them sitting on my workbench, aside from the cases which are definatly NOT the same, the 1-2 and 3-5+R Gear stacks look to be identical?!?

SO, Am i smokin somthin? or can i actualy take the gear stacks from the 96, replace the barrings and put them in my 91 case?

I looked at the http://www.courtesyparts.com site and it seems that they definatly have a lot of the same parts... But before i go throwing more cash at this thing, i need to hear from you all!


Below are the links to the two trany diagrams.

Ok so i DID call them to ask, but they want me to have the VINS which i do not have both of them at the moment because im at work... but Warren recomented I ask here too, and since i was gonna ANYWAY...

Here it is..

kk your turn.. let me know... good news please!!!

I believe the gears are the same, the trannies are nearly identical so most of the parts should swap over. I do not see why the RS5F50 would have many different parts

only difference I have found is the final gear is different

^^^^ In that case (no pun intended), why not change out the diff too? I'd say do it. Only concern might be the shimming of the gear stacks in the 'other' housing. Or, will the 96' 5spd bolt up to the VE30DE ??? If not, then switch out the gear sets and diff and use the 91 case.

he said 91 so it's still the vg. iirc, the vg and ve MTs have different bolt patterns. however, i do believe you are correct in that the vq and ve MT have the same pattern.

No, the VG mt/ VE mt transmissions have identical bolt patterns, the ve mt swap is a very popular mod with the vg 3rd gen owners..

The VG mt/ VE mt gear ratios are different, not sure which gears are different, but i do know 5th gear in a vg mt is about 500 rpm lower @ 70mph vs. the VE mt trans @ the same speed..


No VQ trans will bolt up to any 3rd gen engine, VG or VE, the bolt patterns are different.

^^thanks for correcting me! boy i was totally off, lol. now that i think about it i do remember reading about ve swaps amongst other 3rd gens because of the stronger gears and vlsd.

i am pretty sure that the internals of the ve and vq MTs are supposed to be interchangeable though. and seeing the specs from ben's post, i don't see why they wouldn't be.

Greeny

Yeah, iirc the internals are pretty much identical from VE/VQ manual transmissions.. The automatic VE/VQ are also identical, just different casings.

so what about the shafts? length? etc? could i swap the entire shaft between the two?

if i leave the final gear (the diff) alone it *should* work? *may*?

if i wanted to swap the final, i am assuming that id have to swap the drive lines?

Here is what you could try for no money at all, swap the clutch housings from the tranny. Put the 91 clutch housing on the 96 gear stack. If it bolts up you just solved all your problems for free.

ooppsss .... Not a VE

I am corrected! lol

Let us know what ya do ... I'm curious.

well im gonna go buy a larget micrometer and measure everything and figure out which bareing kit i need. I have both trannys apart on my workbench right now. As soon as i figure it out ill post an update.

Check with the retailer and see if the bearings are the same, my guess is they will be, but likely a different part number (more $$$ in it that way sometimes).

cvsmaxima

i did that already and got differant part numbers and prices. Thats why i asked here in the first place. Even the guys at http://www.courtesyparts.com/ recomeneded that i ask the forum (especialy ppl like you that have a bit of experiance in this department) what yall think.

I know i SAID i was gonna get the micrometer and take some measurements, BUT i spent the weekend rewiring my breaker box to add a new circuit for my spa so i can finaly hook the damned thing up.

So sorry, I havent got that done yet.

Perhaps some evening this week :-/

hey, something interesting... in aaron's 3.5 in a 3rd gen thread, he used his 3rd gen se trans with a 4th gen tc housing so he could mate the trans with the 3.5. his was auto (and ve) but i wonder if the bell from the 5mt 3rd will match up to your spare 4th gear housing. worth a shot if you got everything right there.

Interesting point... hmm.. ill check that out, but since im here i wana do the barring replacements anyway, so i really need to get that micrometer on the thing and find out.

From a previous post, the only gear differance is in the final, so i also need to find out if i need to leave the final or replace it. (i want to leave it i think jsut so i dont have to find a new set of axles.)

ill let you know what i find out.

im fairly sure that it will bolt up, what im NOT sure is how snug the barrings will be. i dont need them flopping around in there.
