Hi Guys.

New owner daft question coming up.
I have just bought a 2002 2.7 CRD.

Can you tell me how long the dipstick should be for checking the Transmission levels.

Bought one from EBay that says total length 92cm.
Checked the box today and there is nothing showing at all.

Went back on EBay to check and the same seller sells another that is total length 122cm.
Both items are listed for the 2002 2.7 CRD.

Which one is correct as I don't want to add a load of fluid and overfill the Gearbox.

Levels were checked with after a short run with the engine running and the Gearbox in Neutral.

pull the one that's on your jeep and measure it !!!

unless you only have the bung


you might find it is only checked when a service is performed on it, then a set amount of oil is used (7ltrs ish??) so no dipstick required by owner, or the garage lost it

there could be a special tool used by the garage to check the level but that could be pricey, not sure if a DRB scan tool will confirm transmission oil level.

Buy a long after market stick and make on to suit the correct level in your jeep post service, special tools might be required to drain the system

Thanks for the reply but mine does not have a Dipstick form the Factory, just has the Service Cap that's why I bought one from EBay.

Like I said there seems to be 2 different lengths on Sale so I'm after knowing if I have the right one.

You need longer one. Also to mesure the level accurately you need to know the transmission oil temp and have the little chart. I downloaded one but cant find it know.

FSM states to use Oil Dipstick 8863 which will be a Miller Tools number. Googling that you need a 1200mm Merc 722.6 dipstick.

STANDARD PROCEDURE - CHECK OIL LEVEL

(1) Verify that the vehicle is parked on a level surface.
(2) Remove locking pin (1) (Fig. 111). Remove the plate of the locking pin with a suitable tool and press out the pin remaining in the cap downwards.
(3) Remove cap (2).

WARNING: Risk of accident from vehicle starting off by itself when engine running. Risk of injury from contusions and burns if you insert your hands into the engine when it is started or when it is running. Secure vehicle to prevent it from moving off by itself. Wear properly fastened and close-fitting work clothes. Do not touch hot or rotating parts.

(4) Actuate the service brake. Start engine and let it run at idle speed in selector lever position 9P9.
(5) Shift through the transmission modes several times with the vehicle stationary and the engine idling
(6) Warm up the transmission, wait at least 2 minutes and check the oil level with the engine running. Push the Oil Dipstick 8863 in up to the stop and pull out again, read off oil level, repeat if necessary.
(7) Check transmission oil temperature.
( 8 ) The transmission Oil Dipstick 8863 has indicator marks every 10mm. Determine the height of the oil level on the dipstick and using the height, the transmission temperature, and the Transmission Fluid Graph (Fig. 112), determine if the transmission oil level is correct.
(9) Add additional oil if necessary. Use Funnel 8908 to add oil.
(10) If the oil level is above the correct height, use Pump 8910 to remove the excess oil
(11) Re-check oil level as necessary.
(12) Once the oil level is correct, install a new dipstick tube cap (2) (Fig. 113) and lock pin (1).

Same as on my 2006 Grand Cherokee. I got a cheapo wire one off ebay and found the right chart and measured it using an infra red thermometer to get temperature (or a good estimate). I measured the cheap dipstick to know where the fluid should be up to at normal operating temp and put a small paint mark on it.

I wish they had just given a dipstick with the Jeep - my XJ is so much easier!

That's because XJs rock

Thanks for the replys guys. Will give this ago at the Weekend.
Don't have any way to measure the Temp but will give it a good run down the Motorway then straight onto the drive and check the level.

[JamesH]

Infrared thermometer was about £12 off eBay. That's cheaper than a litre of gearbox oil

[Jon G]

Well checked the levels this Weekend and it took 2ltrs to bring the levels up to the 80Degc lMark.
Guess the next thing to do is crawl under it see if I have a leak anywhere, as that was a bit more than I expected to add.
I'm the plus side though the Car does seem to drive a lot smoother then it did 

[macabethiele]

That's a lot of fluid to add, if you overfill it slightly it will usually  cause slurred / flairred gear changes and can break the gearbox if it is seriously overfull.
