I am about to buy an automatic Mercedes A-160 & the seller has told me that the gearbox is Damaged. I am a First time buyer who knows nothing about cars!!! Or the cost of repairs. Below is the description given:
"The car itself is fine other than the fact that when selecting drive or reverse, it displays a fault code "F". You are still able to drive it, however, it goes into 'limp home' mode where you only have 2 gears. 1 drive & 1 reverse. the engine does & has always run well."
I would like to know 3 things please:
How much roughly would it cost to repair this problem?
How much would it cost to replace the gear box completely? (as appose to a repair).
Would the repair & replacement costs apply to both Manual & Automatic Cars?
Many thanks for helping to understand this, I look forward to hearing from you.

Most transmission repair shops will have a exchange box that has been reconditioned and will take your transmission as part payment. If you buy a junk yard transmission you may have trouble in a few months time.
I cannot tell you why it happened untill we find what actually it needs to fix it,,,,,Is your check engine light on? If it is forget your high priced mechanix and Go to your local auto Zone parts store and ask them to run the scan coder on your car,,,its free there and they wont lie to you,you will get a paper read out and they willl explain the codes that came up and tell what you need to fix the problem.Soubnds like a sensor that controls the shifting of your tranny is bad,,,,Why?,,,Your car is 21 years old,,something is always going wrong with old cars.A car is only good for 5 years than things start breaking down.Fix only what the code says is wrong and get rid of that old car before it becomes a money bucket!
The code is consistent with an electrical short within the shift motor solenoid. These solenoids open and close fluid passageways within the gearbox that cause clutches engage and disengage with the planetary gear system that make up an automatic gear box. Auto boxes are very involved pieces of machinery and best left to experts so I am afraid it needs a trip to the Mercedes dealership or a good auto transmission depot. It could be that the gear box can be easily renovated by fitting a new solenoid in which case an overhaul rather than replacement will be the cheaper option. Since you have the code for the fault I would phone around for repair quotes.
The gear box and the engine are separated by a clutch and flywheel in the manual and a torque converter in an automatic so I am little puzzled as to how water (presumably engine coolant) got into the gear box. That aside, the only remedy is to drain the gear box and replenish with new oil.
On the other hand do you mean that water is the engine oil if so this will need to be drained and renewed. The only source of water contamination in the engine oil, other than the inadvertent adding of water via the oil filler cap, would be a cylinder head gasket failure allowing water to leak from the internal passages into the oil ways. If that is the case the gasket will need replacing.
The problem seems to be originating from your gearbox. The gear box has two main components that convert the torque of the engine to the tailshaft; the 'torque converter' and the 'bands' within the gearbox. If at higher rpm the car starts to rev higher and slow down then it would suggest that one of these two components are slipping or not functioning correctly.
To fix this problem you will have to take your car to a gearbox specialist who with either reccomend a replacement gearbox, a overhaul of the orriginal gearbox or if you get lucky a new torque converter. Unfortunately this car be a costly opperation but is quite important in reguards to the life of the vehicle.
Dose the clutch pedal drive in gear 1" from the floor OR 1"" from the top when you let it out. if its drives when almost out and there is a vibration on the pedal then the clutch needs replacing and it has nothing to do with the gear box or oil
But the gearbox has to come out before you put a new complete clutch in
I have a 2002 X type (2 litre. done 44000 miles), dash showed gear box problem, (red circle light up). I pulled out and turned the engine off. 5 minutes later turned the engine on. The engine running but the car would not drive either in drive or reverse. Turned the engine off again and on the car driving but not much power. The care is taken to the Jag. dealer and told is misfiring + some gear box faults. Suggesting to change some coils and see (cost about £200+). also possible need to change the gear box costing about £2500+. Please advice. Shall I go ahead with the repair? Should I part exchange.
Hello, I have worked on Mercedes for the past 20+ years and I can't think of any way to do this easily. The shift lock is tied into your steering lock/ignition lock for safety and theft reasons. I hope this helps. CYA, Gator241
Gearbox -> Synthetic automatic transmission fluid
Differential -> Either 90W engine oil or 85W90 gear lubricant
Engine oil -> Not really sure of the weather in Uganda but I take it it stays pretty warm all year long, probably 20W-40 or 15W-40 synthetic
Spark plugs -> Well there could be a long debate over that... if you're having engine performance/missing problems i'd try replacing them right away but with any gasoline ignition system i try to replace the plugs about once a year... plug wires about 5 years... regardless of condition. In my case, i don't usually go for expensive "platinum" or whatever kind of plug that costs about 10 times as much and usually don't do much of a difference... I'd rather buy reasonably priced spark plugs and replace them regularly, and get a much better result and more money in my pockets... because even if you did buy the expensive ones you usually end up replacing them at about the same time you would have the cheaper ones, with the same effect
