Jatco fluid change – success!

I used the LRN402 stuff from LR. At the time we didn't know of any alternatives. It was too much of a risk for me to use anything else. Fekin up my replacement auto which cost me £2200 fitted weighted heavily on my mind. Hence why I insist manufacturers should list the Freelander 1 jatco on their websites if their oil is suitable. If they put it on the tub indirectly as a LRN402 replacement then there's nothing wrong with something more formal on their web site listing the jatco. I have nothing against peeps using alternatoives. I still remember the jerk as it changed gear coming out of bnq and having to pull over. Oil leak = low oil = torque convertor cavitates when air gets in = destroys it = £ or scrap. I used the standard drain/refill which changes about 42%. I did this 3 times with approx 200 miles inbetween. The LRN402 smells nice too.

I understand your concern about alternatives to the LR stuff, but what is in the LR bottle anyway? It was Texaco N402 as they supplied Rover and LR with oil for the Jatco box. The Texaco N402 was superseded some years ago now and is now called Texamatic 7045!! It's more than possible that this is what LR supply in there bottles now anyway. In imho it's better to use a better quality fluid than ether putting a change off due to the cost of the LR stuff or by using a now out dated mineral based fluid.
 
Great post by Singvogel, I'm just about to do this to my Freelander 1 2.5 V6, due to recent problem with a line pressure duty solenoid, changed out with new due to harsh gear shifts. I will post more detail about this in a different post, unfortunately I did not take any pics of the job. It was a nightmare but alot cheaper than the 900 quid quoted by the local gearbox specialist. I will also include in the post my attempts at the oil change, be it successful or not!!

It's not difficult to change the box fluid. Just follow the posts. I've done mine twice since November.
 
Very true Hippo - no pics in my thread - but that was because I couldn't improve on yours with the arrows and such. ;)
My no pic's :eek: was for tomr2002uk but me web connection keeps dropping out as they're messing with it so when I got round to posting it again I forgot the quote bit. But I'll let him oft as it's his first post.
 
Hi,
I'm about to change the Auto trans fluid on my Freelander 1. Can't find the fill plug - what I have found is a vertical steel pipe coming out of the top of the box which is then cranked over at 90 deg. It seems to be in the location where I expected to find the filler plug. There is a raised boss on it so it's made to accept a pipe. Outside diameter is 6.5 mm. It's on a 56 plate, one of the last Freelander 1. My point is, it's not a pull out plug, but a pipe. Is this a fill pipe or should I keep looking for a plug. It's uncovered at the inlet, a worry, as all sorts of muck could have entered the box.
Thanks, Pete
 
Have you read all this thread ? If not I suggest you do. Most important you don't remove the incorrect plug or you will loose reverse gear. Not a simple job like autos with dipsticks so read up first.

Yer describing the small breather pipe on top of the auto. It is an air breather and not to be confused with the auto filler. The filler pipe is at the front of the auto at the top and has a rubber bug. Picture of the filler in the fred below. For some reason I can't see pictures or graphics so can't post the exact picture. Make sure yer following the process correctly. If yer don't yer will fek yer auto up. Make sure yer undo the correct bolts anorl.

couldn't agree more, i done my auto oil change and followed the full instructions to the letter,

made a big difference, made it quieter and smoother, plus as I didn't use mine from day to day gave it a good run out, going up and down hills etc to get the max amount of gear changes out of it to ensure all the solonoids were operating correctly

then the next day rechecked the oil level and was spot on, know it doesn't need doing but change my autobox oil every year, know it's an overkill but do it at the same time as the engine oil, filter, diff, ird etc as I thought if something goes wrong at least I did all I could to prevent problems
 
This useful thread deserves a bump!

Ravenol now lists an auto fluid suitable for the Jatco. Not cheap, but it is an alternative.
Inch Measurements!
I must be ancient as in the bottom drawer of my tool box, way in the back I have a box of Whitworth and BSF wrenches and sockets.
I may even need them again one day! :D

This may be my last bump as I have traded my Freelander for a ZT190. I am just doing a service for the new owner before he takes custody of the Hippo.
I may well be stopping by as the MG has a KV6 so I know there will be adventures to come. No Jatco though! :)

Thanks to everyone for the useful tips and how-tos and for the great fellowship over the 3 years I have posted here. You're a good lot!
