Anyone do a 5MT to 6MT Swap?!
Anyone do a 5MT to 6MT Swap?!
Sorry if this has been covered but I'm new and searching seems to only turn up AT to MT swaps so...
I'm still trying to iron out the wrinkles on my newly aquired '00 SE 5MT I purchased a couple weeks ago. I'm slowly but surely making some progress only to get kicked in the ***** with my discovery tonight. Apparently my Max is the victim of the dreaded diff bearing failure...driver's side axle is loose and leaking. Since a replacement seems eminent the question is do I swap in a 6MT? What will I need as far as parts? I bought this car to replace my '06 Spec V (it's too small) and really wasn't looking forward to giving up the HLSD 6MT. Maybe this way I can have my cake and eat it too...
If not, which 5MT do I look for? Finding either won't be a problem, my neighbor runs one of the local salvage yards and is swap-friendly and savvy enough to find what is needed.
Your input is greatly appreciated.

Well you are probably going to be told to search because this has been discussed before, but I have been thinking about trying to acquire the parts for the same swap so I will respond. I want to do it to further improve my economy. My 5MT/clutch is in good shape at the moment so I have time to gather everything and get down to it when I decide.
Everything I say has been gathered from what I remember from having searched on the topic myself, you would do well to verify it as I have no actual experience with this yet.
I am a little confused as to whether you still have the Spec-V and are proposing to take the 6MT from it? If so this is possible, however, the bellhousing on the Sentra tranny is different from the Maxima so you have to take the transmission of the Sentra and mount it to the 6MT Maxima bellhousing. The reason people do this is apparently the transmissions are not exactly identical in gearing, the Sentra 6MT has a longer 6th gear than the Maxima. The other advantage is the Spec-V tranny always has the HLSD whereas that was a rare option on the Maxima one so you have to really search around if you want to find the HLSD.
Assuming you are talking about finding an unrelated tranny. The above is your decision. You can buy the Maxima tranny, most likely without HLSD and also save yourself the work of having to do the bellhousing thing.
If you buy a Sentra tranny then obviously you will have to buy the 02/03 Maxima bellhousing. Not sure of the date range of compatibility but I believe the newer Spec-V tranny are the better ones. 06-08 if memory serves correctly (definitely verify that but I do know for sure there are better Spec-V trannys)
The parts you will need other than that are the 6MT gearbox and shifter assembly. I believe you also need the pedals. Not sure about the hydraulic parts or which of the axles you will have to replace (I think both?). The other part you should be aware of is I believe to complete the project you must modify the crossmember in order to mount the transmission (verify that too).

To be fair, there's not really much info out on this, searching could easily bring up nothing.
There's a couple threads on it with details, even a couple DIY threads IIRC. I dont know where there are, but they are out there. You might want to look in the 4th gen section, the 5speed they have is the same as yours.

Ok ok, I'll be nice...

and there are a few incorrect things in FFC's post, when I feel like it I'll address them later.

I have Cattman headers I was planning to install myself.......maybe I'll leave it for a shop

DW
And if the vehicle has never had it's y-pipe removed.....

After that it's really easy to do headers, like silly easy.
6MT swap aint that hard either though...... once you have all of the RIGHT parts.....
Thank you for the link and the added info. After looking it all over I'm not sure if I can afford the down time, but I'm still going to look into it. If I decided to stay 5MT which trans do I try and get to avoid this mess all over again?! 6th gen?
A big 'Thank You' to all those that have posted so far, I appreciate the input.
It took me a week to do headers, and 6 days to do 6mt swap, bear in mind 2 of those days were just "OSH WHAT AM I MISSING" and the other 2 were "OSH I DONT HAVE PART XYZ NOW I GOTTA GO BUY IT."
It can be done over a weekend if you have ALL of the correct parts.
In comparison to other FWD cars, this is one of the easier and cheaper 6mt swaps out there.

You do the same exact thing as the 5th gen... Even though no-one has talked about doing it on a 5th gen.
As for a 5.5 gen it's nearly the same except a little less work because of not needing to customize the flywheel.

I'm confused, wouldn't a 5.5 just be a tranny swap as it already has the 6MT?
