Hmm...the OP himself says that he can feel the 2-->3 shift?

What is a O-P?

------
Update, the left drive shaft 'claimed' to be replaced by the old owner isnt the case.

We found that the left boot was replaced now, Grease is new. So for time being we are opening up both left/right boots, packing with grease and refit.

So as of now both left and right are bust, giving away that kat-kat-kat noise in stop-go initial seconds and hard right/left turns.

I am going to live with that noise until they fall apart.

PS - LPG has been reduced from 49~ to 46~Rs/Liter in my town (Hosur). I am sure the car gives 14+ Average making this not only a easy car to drive, but a cheap car to drive also.

OP is Opening Post/poster

I had a car with the kat-kat sound. Trick is to not give accelerator when the wheel is fully turned. Build up speed and coast as you turn. If you have to, then be gentle with your right foot

Came across a used Zen AT ad in carwale which had a picture of the gear lever and thought it would be helpful for this thread:


800 AT has a PRNDL pattern while Zen AT has a PRND2L pattern. So I guess it is safe to assume they are different.

Good point. I leave it to experts to answer that Q.

Some observations :

1) In (my M800 AT) in D mode there are 2 (or 3) modes + 1 Low range.

2) In Zen AT there are (as they say) 3 speeds in D mode + '2' + L range?

So what does it actually mean when they say 2 or 3 or 4 (santro i10) Speed Auto box?

Is the speed within D mode or D+2+L mode?

All gears of AT are available within the D itself.

The rest of the positions (L,2,3) are used to limit it to first few gears. L ensures the car always remain in first gear, 2 would restrict within first 2 gears and 3 for the first 3 gears. This is helpful when you are in a steep slopes where the transmission would normally upshift due to rpm levels which is not what the driver really wants.

What I meant was that the 800 AT and Zen AT boxes were clearly not the same. Even if 800 is indeed a 3-speed, it is likely to be different from the one in Zen/Esteem. Usually the presence of '2' is an indication that the AT box has more than 2 gears since it is irrelevant when even the D has only 2 gears to choose from. That strongly suggests 800 to be 2-speed.

Interesting ^

Thanks a lot Zenren. I definitely agree the Zen AT and M800 patterns are different does point towards a 2Sp Vs 3Sp GBs. I think I am going to research the European M800AT (weblinks, pics, case markings) for some more info.

The Zen AT gearbox has a 2 position which Maruti mentions as Low-2. According to the manual the position is used to extra power when climbing hills (logic is as stated by Zenren) and also it provides engine braking while coming downhill.
There is another L position which is actually L1 which is used to provide 'extra power' probably by limiting the gear to first, even if the rpm increases. Advised to used when the car is in deep mud/ snow/ got stuck or when in need of high engine braking.

The picture that you clicked of your car shows only L and there is no 2, hence it suggests that the GB may be a 2 speed GB.

The intended user of this car is slowly becoming a expert and NH7 runs (we live bang on NH7 and NH207 intersection - Hosur) are getting more frequent and confident.

The ICE got a little upgrade over the weekend, got 2*6" rounds for rear quarter panel (boot side panels) and front door could take 2 spacer rings and 2*4" rounds (all 4 pioneer basic speakers), good enough for our ears. Costed 3.5K ish.

Got a question for Carburretor-Auto gurus from yester-years...

In this M800AT Carb, the idling has to be set to tad high for the Auto GB not to stall the engine. If I set idle like a Manual+Clutch box, it stalls when I brake in traffic to a full stop. The Auto wants more RPMs.

Is the case in all Carb autos? Or no? Its irritating to always pull the choke/fast idler out and drive all day along. F.E too takes a hit while driving with choke on always.

Will add 1 leaf each on rear susp this weekend. The rear bottoms out too soon with 4 people on board on bad rural roads.

And, what are the tyres (read - cheap and safe) recomended for a M800? I dont want to put in a lot of $$ for a car that I will sell very soon. Would prefer tubeless, please recomend.

Check the below link for an approximate pricing of the different options available:

I have used Apollo Amazer, MRF ZVTS and Bridgestone S322 in the past and is currently using Goodyear GPS2 for my Zen. I found all these to be in the similar league in terms performance, comfort and price. You can probably pick whichever can get you the better deal, depending on the tyre shop you go. Tyre shops usually would have some specific brands that they are official retailers of, which helps them offer a better rate due to lack of middlemen.

Between the Tube-type and Tube-less versions, the price difference is primarily the cost of the tube at ~250 lesser for tubeless. However, think twice before opting for tubeless configuration in case of 800 since you are on old stock rims. Slightly deformed rims would lead to air leakage in case of tubeless. Even a small amount of rust near the valve tube could do the same.

I've not had any issues with tubeless on stock rims in case of both my Swifts but in case of my Zen, I had to put a tube inside the tubeless tyres since 13" rims are prone to bending easily in our pot-hole lined roads. I'm not sure how good the 12" 800 rims fare in comparison but be prepared to buy tubes later in case the tyre pressure doesn't seem to be holding on. Another option would be to use your existing tubes if they are in good condition along with a fresh set of tubeless tyres.

Thanks a lot, I am going to check for cost of new rims right away

I got 2 decent tyres, only 2 need replacement. Might as well put new on tubeless...

Started the leaf addition work on rear springs. All new bushes, 12 in total, plus 4 clamps, 4 rivets and 2 leafs costed 1450Rs in Hosur. Will update after a day or 2 of testing.

[svsantosh]

Took more than few days to report here, eh!

The ride is little harsh in the rear due to the additional leaf, but the height is a blessing over bad roads, absolutely not scrapping the bottom anywhere.

Next work is surely 4 rims and 4 tubeless tyres, 2 punctures back to back and its irritating!

Update after the head work done last month - no heating, coolant level is normal no leaks, water in oil, looks like settling down to normalcy.

Few AT box trivia (may be no-brainer to AT users)

1) From D you can shift directly to N without pressing the gear lever switch and back to D (saves flywheel in idling traffic)

2) From R you can shift directly to D (without switch again), but from D you can go till N not R.

3) From L you can shift directly to N and quickly back to D to comeout of L in a quick shift.


HELP NEEDED

Where is the reverse gear (Light) switch on the GB. I am currently using a seperate switch on dash to activate the rear white light/reversing horn, silly but does the job!

I had given the M800AT to the local M.A.S.S for a bit of tinkering work. There were few holes on the floor and causing rain water to seep in. I went to check on the slow progress and I chanced upon the M800 Service manual from the company.

I think I may have found a gold mine related to this car ownership.

M800 still supports and supplies parts of the rare AT box for this car. I was in a hurry and could click some sample pics, I will post all clear pics later.







Any maruti part number with a "-" means and I have a car with a "-" part in it.

"-" means all Suzuki parts direct import from Japan itseems. Entire AT box is 81,000Rs. Torque Convertor is 31,000Rs. LOL!

I think is the same database that another Tbhpian offered to share with me a few posts ^^

[svsantosh]

The minor tinker work turned out to be a serious patchup work. Lot of rotted places in such a badly maintained car, I couldnt let the car rot, so did my bit to make it run a bit longer.

All rot boils down to owner not spending few 100s on a pressure water wash and all wheel wells were filled with dried up slush mud over the years and dampness couldnt dry up/drip down sooner!























Hopefully she is back in a few days!

[svsantosh]

Full Respray done, painter could not get the original off-white color from factory. Went ahead and got the white rubbed down and changed to current generation white.

These pics are a few days old, as of now all interiors fit and exteriors done. Hopefully back by tomorrow.
