Sorry still being dim (weapon systems I can fix, gearboxes are much more complicated!) The gears, unless the teeth are broken surely cannot slip. The fluid clutch must slip as a design feature, otherwise the vehicle would stall at idle.

I am no expert, but i dont think that the jatco box has a clutch , it has a torque converter. so i dont think its the gears that slip, but someting to do with the torque converter.I might be wrong:confused:
 
i am not going to panic ,i will see what happens when i change the oil,by the way, the oil was 40pounds for 4 litres. rik if your reading this dont panic ,maybe check the level in the box, topping up may cure the problem? nothing to lose!!!
 
thats for the advice. i have been reading many threads on this subject, posted by you, ming, mondo and clucthdust. i must say you have all help me understand my car a bit more and i dont think i will give up on her now!!!
thanks

Hey Minge

Maybe we cud use Ricki to devise defence systems for the pub?

erm - maybe payment in beans?

arternoon by the way ;)

Well just a update if anybodys reading, I changed gearbox oil - NO GOOD!!!!!
I took the car to a garage my friend owns, (he is not a freelander expert, but has diagnostic gear) and several faults appeared, as follows-
p0740- lock-up clutch solenoid
p1605- A/T ecu eeprom error
p0734- Gear 3 incorrect ratio
p0734- Gear 4 ---"---"---"---
p0735- Gear 5 ---"---"---"---

My friend is not sure if all faults are being caused by ecu or if there is problems with internals of the box and a problem with ecu!!
Does anyone have a spare ecu for the auto box ?(i have been told it is seperate from the other main ecu)

Anybody have any ideas??? i am desperate i cannot afford a replacment box, as i am buying a new house and it is taking every bit of ,little, money i have!

Any advice welcomed!!
 
Hi Troy
Sorry I cant help - but I am intrigued by P0734/5 faults - "incorrect Ratio" - not sure i understand how this can occur - but I am someone on here does. ;)
 
Good evening ,thanks for the replie.
I dont understand either, but the fault codes corresponding to 3rd, 4th and 5th gear arent a suprise , because it is only these gears that are affected. What was strange was that when i picked up car this afternoon it drove okay for a couple of minutes and definately did not slip in 3rd gear, but when i slowed down the box dropped to 2nd okay,but when i sped up, it engaged 3rd but started slipping again!! What do you think? maybe not internal fault , just electronic?? GLIMMER OF HOPE ? OR DILUSION?
 
Sound like yer ecu on gearbox is shot, the eprom fault is the give away ,its gone ta default mode but not talkin proper to the ems, ,after a re fit it should clear it,otherwise its back on diagnostics. . . .best oh luck. . .:)

thanks ming, i have seen new ecu's for the jatco box for 75pounds, does this sound cheap

Afore ya go chuckin money at this one,get a proper lr diagnostics, they will be able to tell you what the problem is,if it is the electronic bit on ya gear box[and by wot yer have said thus far,fair bet thats ya problem],you can diy it ,and save dosh . . .best oh luck. . .:) :) :)
 
thanks for the reply ming,
i have spoke to lr and explained fault codes, but they said they cannot soley test the EAT ECU. and rather than spend £80 plus vat for diagnostics, i think i will just get hold of a eat ecu and try that.
