The syncros must come to a stop when the shifter goes through the neutral position if the syncros are to last. Maybe spray all of the connectors with some water dispersant. Many thanks Robert Hi all. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. It's due a fluid change, but as I wash underneath after every weekend of wheeling, I notice that there is some oil residue on some of the under body bits rear of the trans. This gives the best of both worlds, high stays the same for road use, you have stock low for running about between sections and you have underdrive low for crawling over obstacles or winching.
I believe it does this because 4th gear with a ratio of 0. It is also known as the Spanish Box. Offer the underdrive main case to the transfer case, using the gasket supplied, and after fitting the washers and nuts tighten down evenly. Need help with a P0730 code? Thanks Hi have a td5 discovery 2, 02 plate, I have the two gear lights flashing. The transmission may stay in a low gear for too long, or stay in a high gear until the engine stalls.
My Autobox is now only able to select reverse. If I stop I have to start in first again. Shift option will be High or Low 2wd power to the rear wheels. Low or dirty transmission problem is probably the most common cause of this error code. Is there anything else I need to look out for? I would be grateful for any help and advice you can offer. From that information, I gather that any… There are several.
We have all of these tools and many more that we have created in-house. Runs ok but not fixed after a nice bill. You may want to precede the fluid exchange with a cleaner to clean the transmission and especially the valve body of gum and varnish deposited from the old fluid. What repairs can fix the P0730 code? I never high pressure wash under my car, no probs on the D1 but not worth the risk on the D3. Small problems with the wiring, common in aging vehicles, can easily trigger certain trouble codes without the presence of a serious problem.
The new fluid seems to have helped some but has not resolved the problem completely. The governor valve is sticking, which can be caused by contamination. If there are other transmission code problems, they should be fixed first before fixing the incorrect fear ratio code. The gearbox oil is drained and the sump and gearbox oil filter are removed and inspected along with the sump pan for any debris and swarf. This gearbox was used as originally designed until 1988.
A little Automatic history 1982: the Chrysler 3 speed automatic transmission was introduced into the Range Rover product line. When the P0730 code appears, it often does so alongside several other error codes. Many thanks for your help and assistance with the above, Sean. Make note of the fluid condition, clean and pink or burned and brownish. It is used with permission.
A rebuild is required to correct this. Is there a list of possible compatible gearboxes accros the Land Rover range? Any idea what could be the problem here? For whichever route gets taken, the labor will be expensive, so it is best to make sure the transmission actually needs to be replaced before adding even more money to the bill. The fine debris finds its way past the filter and tends to accumulate in the governor, causing it to stick. Depending on the severity of the issue, the technician may perform a torque converter stall speed test to determine if the engine stall speed is within factory specifications. Goes into 1 and 2 fine but it will still stay in 2nd if i shift it in 3 or D. Be sure to rule out all other less expensive possibilities before replacing the transmission.
I have changed the filter and oil and also added Lucus Gearbox Treatment, to no avail. If it is necessary to reset the preload change the shim behind the bearing cone. The intermediate range is a useful gear split between stock high and stock low High and Low ratio will remain unchanged but when selected the underdrive will give an additional 2. The torque convertor must be fitted to the gearbox, located correctly on the pump and locked into position before the gearbox is offered to the engine, otherwise damage will occur to the pump, resulting in no oil flow and subsequent to other parts of the autobox. If the fluid is low then add fluid but under no circumstance should the fluid level exceed the full level on the dipstick.
This seems to briefly solve the problem but only for a couple of minutes. On the test drive pay close attention to the shift points for all the gears, and notice any slippage or any other problems under different throttle pressures. To see a review from AustralianCar. The serial number will be stamped in one of 2 possible places, either on the bottom left of the main casing or on the earlier vehicles right at the bottom of the left hand side face of the main casing obscured by the exhaust pipe in which case you will need a knife to scrape the muck off and a mirror. Is the oil cooler not working correctly or was the first two repairs not done properly?. But suddenly, while I was driving it, my disco lost all traction. We also have the ability to drive all the vehicles on our 4x4 Rolling Road Often called a Dyno or Chassis Dynamometer There are not many companies that have access to the facilities that we have available.
Runs fine for a while then does all manner of insane up and down changes — tar travel only. Remember to take adequate safety precautions like applying the park brake, etc. The fact that any abnormality in the transmission speed will trigger problems to the gear, the severity of the problem can vary. A common mistake leading to early demise is running 90wt. Cheers Hi Dave Just got a rover P5B 1972 automatic box.
