If above statement is not TRUE, then why did the THAR come with manual TC?

i said converting a electric shift BW to Manual with some jugad is not recommended.

we can always swap the whole TC with manual shift TC any time.

yes the electric TC is not reliable as Manual BW.

The word 'high' is not the exact word for that , but YES there are issues WRT waterproofing ( even splash proofing ) . & there are some known problems .

You need to 'Thank' DB Sir for this I know certain 'people ' wont like the 'Thank ' thing here -- but Apologies in advance

Jokes apart but 'He' must have faced such things or knowing it in advance so its possible that he preferred Manual shift , I think he can explain better .

@Sudharshan Jee: The electric shift uses motors to do the shifting, hence there is a small delay between engaging 4wd and the actual locking of the front axle. Also it was prone to a lot of problems because of incorrect design in the concerned vehicle and M&M knew little about it.

In the wishlist thread, many had indicated the requirement of the good old manual 4wd as it appeared fool proof and better than fancy electronics!,

Hence the THAR has manual TC GB.
BTW, did you notice the placement of the TC lever on that vehicle?

Headers Sir : Its really difficult for me to comment upon the Borg Warner Transfer case ,( with respect to the above ) . Because I have a very limited interaction with the said transfer case ( Product ) & that too on paper ,though I will connect with the Trabsfercase Wala & try to find some answer through the horses mouth

Sir the said thread is a subject of experts , so I will again refrain from commenting & there are enough people here who can actually suggest any improvement . I lack field experience to suggest any improvement

No Sir- I didn't notice that but I will check that as you say so , but I have heard some badly adjusted linkage affects the performance

Dear all -

Thankyou for all your suggestions and recommendation. Special Thanks to Ashish (whitemm550) who helped me reach to some one in BorgWarner, Suresh Stephen for his patience and passion and Swastikviji for helping me with Ramesh's number)and Bebeoy (advised on part availabality in Chennai).

Firstly after speaking to some of them, i gave up the idea of either replacing the ECU or getting it repaired; not worth the cost, effort nor reliable.

Second, a manual X-Case wasn't available cheap as well. One of our BHPians quoted 40k only for the used BA-10 gearbox and x-case !! So gave up !

Spent some time with Suresh at his residence understanding the mechanics of this 4x4 setup and probable solutions (he was kind enough to crawl under the jeep to examine and explain !). I promised him, i'll discuss with a fabricator and keep him posted (Sorry Mr.Suresh, i decided not to go with the pully mechanism for i found an easy alternative )

In my eagerness to fix this issue, i found this website 'www.theshiftster.com'; and that's it ! bought The Shiftster got it shipped (thanks to a friend who was visiting) !

Got my hands on the Shifter 3 days ago, fixed the setup myself today and my 4x4 jeep is good to go ! The pictures below should explain the rest.

"
Next Steps :

This was the easiest and the most cost effective solution i was able to find. The mechanism is easy to explain to others who may drive my jeep. Luckly the Trabsfer case is positioned exactly inbetween the front 2 seats. I plan to visit a tinkerer and ask him to neatly fabricate a Flapdoor, (may be like a fuel tank door) this way either i or the person next to me can engage right from sitting inside the jeep.

Currently its difficult to always step out, duck down, crawl to reach the shifter; also with the hot exhaust pipe close by, good chances of getting a burn. Hope the internal door helps. From what i see, i do not even have to bend from the driver's seat, to reach the shifter as its right below the floor.

Again, thanks for your recommendations ! I'm back with a solid and reliable 4x4 !

Regards
Charan

thanks for the information !

please post the pictures here.

this is very useful but with this you loose the onfly shift ability.

BTW i am not sure about the door on the floor due to position & distance of the shifter from the person sitting on the seat.

but if it works out many offroaders will thank you.

rgds,
Nikhil

Thanks Nikhil

I'm unable to post pics as i think i am still a newbie, meanwhile please follow the picasa link; will post pictures of the flap door once fabricated, maye be over the next week end.

@charan:

Excellent job with the T-case. Mahindra should really stop offering the electrical transfer case, if they cannot service.

Where did you get the BFG tires from? Are they 15 or 16 inch?

Charan has shared some excellent info , thanks to him

Dear All & Charan
putting a drawing for your thinking , can a cable mechanism consisting of Inner & outer cables be used to rotate the shifter knob ??

There are two cables to rotate the disc , when one cable pulles the other is idle so each cable rotates the knob at different direction . Also there will be a lever in the cabin attached to these cables to pull them

( this has been inspired from the shifting mechanism of the geared scooters )
I dont know how effective the cable controll be , but people involved in doing the setup can think over it

Sudarshan Jee: I bow to you. The shifter designed by them is a positive locking mechanism. Cable solution will work but what about the slack that develops over time and what if the cable gets cut

One of the primary reasons for development of this device is because of the unwarranted failure of the electric shifting mechanism. Thats why they have a manual knob to do the shifting - anyways!!

A spring loaded ball can be used for indexing a position on the disc

Also a third cable can be used to activate/deactivate a spring loaded safety latch .

adjusters can be added to outer cables to take up the slag & heavy cables like the front brake cables from bikes can be used

Observe the bajaj or lambretta scooter gear shift mechanism for this ( my original inspiration )
