Thanks.
I did the stall test today it it passed so now I'm getting confused. Will have to try and find where they hid the ECU over the weekend. She runs fine just the Torque converter won't lock up.

I suggest that you go on to the Outer Limits forum and ask Ashcroft, who AFAIK is the biggest ZF rebuilder in UK.

To my knowledge the ZF uses a solenoid to lock up.

Hey Ladas it's Turtle here. Well it was as I have just sold it. You should remember me as I was the one who blew a gearbox at the NE Vic meet. I can tell you that the ZF on the 300TDI is definately a hydraulic lock-up converter. I had recently replaced mine. From memory the TD5 is also but I may be wrong. My advice to start with would be to check the fluid level. If you need advice from the guru's of ZF in Melb, call A and B automatics in Dandenong. They will put you on the right track (so to speak).

Turtle, have you sold the Disco? See my PM to you - I was interested in it.
