Thread: Discovery 3 Transmission Problem

Shatter??


Or shudder??





Moved to the D3 section.

This is a common problem, and many users have reported the problem. It's been said that the torque converter and / or the clutch plates go bad in them. Some say a double flush will fix the problem, or accelerate the demise. I talked with my guy at Centurion Gearbox and Diff and he said;

On your previous mail you have asked me on 6HP transmissions?
What we experience on the Diesel models more frequent as on the V8 models was a Torque converter SHUDDER feels like a vibration under load in 3rd gear accelerating, this was more an oil viscosity problem not Torque Converter failure although TC replacement was the cure.
The lock-up clutch plate inside the TC had an abnormal shine to it (Glazing as we would call it)

We are in the process on rebuilding these TC as there weren’t clutch plates available. I would phone my supplier for some more info on Lock-up clutch plates availability.

Hi All I have a D3 Deisel 2007 and recently it has begun to shutter when under load going up slight inclines. My mechanic diagnosed this as the torgue converter and quoted $3500 for replacing the torque converter, replacing the transmission sump with a steel one and replacing the transmission fluids. Does this sound like a fair diagonsis and price for the repairs? Look forward to your comments, thank you in advance. Clancy

Can't tell you about diagnosis or full cost, but just the flush and steel pan cost me about $1000.

I think that if you are keeping the D3/LR3 I'd be doing more than just the TC / Fluid change.

As mentioned the alloy particles would be in most of the solenoids, I'd be replacing them at the same time.

Do a google search on ZF 6HP26. They are in lots of vehicles and are pretty well regarded. It might help identify likely problem causes.
