I personally think it is not possible, but the best source for this query is Mr. Behram Dhabhar.

Basically you are moving a shaft fore and aft to engage/disengage 4x4/Low Range so a good mechanical enginer should be able to design a direct shift lever.

The NGT520 which is loosely based on the BA10 has a direct shift so you can look into the option of adapting the shifter for the NGT to the BA10.

Hi do you know any good mechanical engineer who can do it ? i know it can be done, their are plenty of spares for BA 10 direct shift in M&M parts database. but exactly don't know how to do it this isthe part number as printed in Mahindra 2007 parts data base : 92677 T/M ASSY BA10-2WD DIRECT SHIFT.

Ok jeep gurus no answer from experts means its not possible. now tell me that which 4x4 gear box is suitable for my 550 without changing crown pinions and Shafts. i am not ready for any major alterations in mechanicals.

Vijay sir, In my personal opinion always go for KMT90 gearbox for a perfect offroader. As of today we don't have any alternate option to this KMT90. It is best suites with XD3P, all you need is to replace it with the propeller shaft.

I don't think you need to worry too much about the mechanical as the same combination is used in Army spec MM550.

What you will loose by replacing the BA-10 with KMT90 is that the overdrive that comes with BA-10.

What you gains is something that BA-10 cannot give you ever, DEPENDABILITY.

Sourcing parts for KMT-90 is way easier compare to BA-10 with transfercase.


KMT-90 --- is the best.

Hi Shiva
Can you please find out from your dealer is their any good condition gear box is available with him and price.

Changing the gearbox will involve changes to the gearbox mounting as well as a change in the rear differential. The NGt's are great gearboxes but the 4wd versions are exceedingly rare.
Your old gen BA10 has a side shifting mechanism which is a pain as it has a lot of linkages. What I suggest you do is buy a NGT 520 2wd gearbox (about 15K) and replace the last housing of the gearbox with that of your BA10 4ws gearbox housing. This will in effect give you a NGT520 4wd gearbox.
Hope this picture helps.

Though iam not a jeep guru, I strongly feel donot spoil your existing gearbox by giving it to some one who will experiment with it. Instead please sell your existing gearbox if you cannot live with it and BA10's command good price with 4wd. If reliability is the key then go for a brand new NGT530 one from Mahindra. (since yours is XD 3p) Will give you service for years.

P.S- Dont go for KMT-90 second hand gearbox if you travel long distances. Though this gearbox is super stong but NVH levels are pretty high. Put it only if your vehicle is driven for short distances and is for pure off roading.

Thanks a lot, this is what i am looking for, my gear box is perfectly ok, only problem is that shifting mechanism as you explained, have you done it? how good it is.

I was very upset when I first saw the gearbox (Old BA10) with all those linkages(I had purchased the gearbox without even seeing it as the dealer was a well know person). The gearbox was also faulty, which turned out to be a blessing in disguise, as the dealer got me an NGT530 gearbox as a replacement. I removed the rear housing from the BA10 and fitted it on the NGT 530. Now I have a 4wd NGT530 with direct linkage.
The rear housing is a direct fit with no modifications. However you need to get a NGt520/530 gearbox with aluminium housing. The cast iron NGT's do not have the 3 piece housing.

Hi vijay
I heard that you changed to a brand new engine as your old one sucked some water. That was pure bad luck. Going for a new engine was a wise decision as you intend to keep the vehicle for long time.

As far as your gearbox goes if shift quality is the only problem, then i suggest you live with it. Else i have solution, why not exchange with my KMT-90 4wd? You will know how good or bad your existing gearbox is!!

p.s- You have to be really lucky to source a good second hand NGT 530 2wd gear box for you to add your transfer case to it as jyobeb suggested. Happy hunting till then
