Thread: D2 Td5 accessing the automatic transmission controller ECU?

Yes
Regards Philip A

X2 yes , it's under there, but an educated guess if original for yours would be IGG00070

So did the auto ECU also go through a revision change? I believe the d2a auto had an extra clutch pack and I had always wondered if the ECU then changed as well, I've got an eu2 with a d2a auto and wondered if the ECU should have been changed as well

Looks like it might be easier to remove the seat then to access in order to get the amp etc out of the way.

There are three different options for the Td5 depending on your VIN:

UHC100240 - РЕГУЛИРОВКА ТЯГОВОГО УСИЛИЯ (ELECTRIC CONTROL UNIT-TRACTION CONTROL HIGH COMPRESSION TRACTION CONTROL) [ - (V)XA232916 ] Замены UHC100360 - > РЕГУЛИРОВКА ТЯГОВОГО УСИЛИЯ (ELECTRIC CONTROL UNIT-TRACTION CONTROL HIGH COMPRESSION TRACTION CONTROL) [ (V)XA232917 - (V)YA258481 ] Discovery Series II 1998-2004(1998 - 2004)/BODY ELECTRICS/ECU-GEARBOX & TRANSFER BOX

UHC100360 - РЕГУЛИРОВКА ТЯГОВОГО УСИЛИЯ (ELECTRIC CONTROL UNIT-TRACTION CONTROL HIGH COMPRESSION TRACTION CONTROL) [ (V)XA232917 - (V)YA258481 ] Замены UHC000010 - > РЕГУЛИРОВКА ТЯГОВОГО УСИЛИЯ (ELECTRIC CONTROL UNIT-TRACTION CONTROL HIGH COMPRESSION TRACTION CONTROL) [ (V)YA258482 - ] Discovery Series II 1998-2004(1998 - 2004)/BODY ELECTRICS/ECU-GEARBOX & TRANSFER BOX

UHC000010 - РЕГУЛИРОВКА ТЯГОВОГО УСИЛИЯ (ELECTRIC CONTROL UNIT-TRACTION CONTROL HIGH COMPRESSION TRACTION CONTROL) [ (V)YA258482 - ]

That part number doesn't work for me in Microcat, but there's some for sale on eBay which also have the correct Land Rover part number of UHC100270 on them which Microcat advises is for a Range Rover P38 so I'd be suprised if that's what I have fitted in my Td5 D2a.

Yep , they've gone through a few but not sure what the differences are, but would hazard a guess at increased base line pressures as engine outputs increased, possibly shift point tweaks and lower lock up speeds with the V8's .
Never heard of an extra clutch pack in the d2a , where did you get that info?

Well, quite a few places actually, but I stand to be corrected

Those p/ns you posted are all for V8s , the td5 p/ns are all starting with IGG and it's not mentioned compression for them, you didnt find the IGG00070 cos it misses a 0, it's IGG000070

That was my mistake / typo , re the IGG000070
Yep , low / high compression is loosely D2 / D2a as I've explained in the other thread
