Blown transmission hose

[Shazza50]

Yesterday hubby and I did a bush mechanic repair on a blown trans hose that our mechanic had not clamped or crimped after our tranny service last year. Amazing how you can put together a repair kit from household items sourced from a local general store! We were in an isolated area without phone reception (luckily for our mechanic!) we had fluid on board & replaced about 3 liters of fluid & rue clamped with hose clamp & managed to get back home with slipping and no gears at times! Would any permanent damage have occurred from this and can we just get away with replacing lost fluids and maybe another filter change? Hubby said that when he was topping up dark fluid coming out not red and the car indrivable now. Disco Tdi 5 1999 model. Reluctant to use this mechanic again!

Dark fluid is a good indication that you have "burnt" the oil due to overheating. Permanent damage may have been caused.
Are you certain that the mechanic changed the hose? The tranny hoses are prone to failure at the crimp points. If you had just a service performed I would doubt the hoses would have been changed.

Yes this has happened to me out of the blue as well, so it may not be the mechanics fault. If you drove with low ATF levels you may have noticed the ATF temperature light on the dash illuminate. Almost certainly, just topping up the ATF (a very difficult task lying on your back in red dirt) would not have filled it adequately, hence the reason for the car driving abnormally. Under those circumstances the ATF may have cooked and turned black.
Now you need to have the ATF drained and replaced, and keep your fingers crossed.
After this happened to me I fitted a dip stick and top filler.

Probably my ignorance but I've never heard about anyone doing that before. How were you able to fit a dipstick and a "top filler" to the auto tranny in a D2 and was it a DIY. Mine just has the normal drain & filler plugs and I often worry about whether I properly filled it.

Thanks for your input! Have been making lots of phone calls to tranny techs and am a little reassured by the fact that there is no debris in the filter or pan but as no one is available locally to check the system properly or scan the computer I now face having to transport Dora almost 150kms to get it looked at! Also have had a 3 amigo issue for a few months now so glad to hear that I'm not the only one in the world with this issue! However due to the fact that no one around here has the proper scanning equipment to check the computer that went onto the back burner! How much are electronics involved in transmission function? Would an electronic issue contribute to my problems?

Question
Have just been talking to my local Auto Trans expert (and he is good), and was asked the question which dipstick/filler would be used when converting a D2a auto trans sump to a D1 to provide a dipstick and easier ATF filling? Apparently there are 2 or 3 different versions? and some or all might need some re-routing to be able to be fitted in. Anyone?

As an aside, a new sump might also provide a solution (ie alternative location to the already welded in nut) for my "exposed" ATF temp sensor problem, which to work needs to be inserted so it picks up at the bottom of the sump to give accurate readings.
I have the Melbourne based Autron Triple AFT temp, engine oil pressure and Amps gauge and the Autron version ATF sensor, unlike the VDO, is quite long and sticks out quite a bit (see pics), leaving it exposed to potential breakages.
One option under consideration is a mini sump protector of some kind, but I haven't started researching auto trans sump protectors yet.
Alternatively, apparently I can use a VDO sensor and have the Autron gauge re-calibrated, but from Perth that's probably more of a pain than changing the sump - plus if we can get some good info on the sump/filler conversion option/s, it might help other members here.

How come your sump is not covered in a film of oil?

Because I had just got back from a Moore River trip with AULRO, the last 20 km of which was travelling down a sandy wet river with water mainly at axle centre height - brilliant!!

Plus have just replaced my engine, all new hoses and whatever else you can think of with respect to the mods in my signature.

I had the sump from a D1 fitted by Ray of Canberra Motor Works. This has the dip stick tube on it and fits perfectly into the D2.

Blown trans cooler lines on Td5 Discos are pretty common.

I would suggest people grab the crimped connection at the end of the steel line where it turns to rubber at the front of the vehicle every now and then and try and twist it around. If you can move it easily, then it is close to blowing off.

After 1999 date of manufacture then maybe a replacement some time back would have been a good idea.

I would hesitate to outright blame the workshop, however it is a good idea to perform checks on them from time to time as it is a known problem.


Continuing to drive it while slipping in and out of gear could be a worse result, I would fit a new pair of lines, filter and oil and then change the oil again in 5000km.

JC, would you recommend replacing with LR genuine cooler lines or get a repair done at a local hydraulic hose specialist?

Mines due for replacement, thanks,

Simon

Due to the fact that repairing them doesn't fully address the issue of the cooler end fittings sometimes failing, then short of changing the cooler for a different one with JIC fittings etc (Preferred) then genuine LR are the go. They are actually a lot less exxy than you think.
