TD6 GM Auto Box - Preventive Maintenance or Panic (part II)

Just been to VMTP to inspect the stripped gearbox

For me it is a great result

Oil burnt and sludge residue
A couple of hot spots on a couple of the plate rings
Most if not all friction plates have sufficient material left on them
Black oil residue coming out of TC
NO SWARF OR DEBRIS IN SUMP PAN
NO SPARKLY OIL

Conclusion

TC beginning to break up on its internal friction plates as suspected at 88,000 miles and no internal damage to gearbox internals whatsoever - valve block to be pressure tested, stripped and resealed

I reckon TC was within a couple of thousand mile from total failure and subsequent internal damage to gearbox

Plenty of pics taken and will be uploaded later

Current results are what I hoped for so am happy bunny !

Update later

looks like a good result then Dave

To be honest it is better than I hoped

I can live with finding black sludge

It was sparkly oil or swarf in every orafice that I was dreading

They say paranoia is the best form of defence!!

Returned to VMTP tonight to deliver the Gen LR oil filter

Box now rebuilt

The valve block assy was stripped, inspected and re-sealed and as NO swarf had circulated through the system the bores were totally serviceable and no discernible wear was evident

BUT

an accumulator spring was found to be snapped (see pic below that was taken from another thread elsewhere and it lists the accumulator as being "overdrive clutch 4-5 shift"

All other pics are my own box stripped and then rebuilt

Jigsaw puzzle ???

I always thought it was by Ozzy Osbourne and Black Sabbath

When Land Rover decided to fit a chocolate Torque Convertor to the TD6 GM Auto box that "alledgedly" was only rated at a fraction above the stock engine torque instead of utilising for example a 20% higher rated unit then in my world Prevention is better than a cure

It is also common knowledge that from new the TC is likely to only cover 80 - 100,000 miles

Oh yes

could do that blind fold! wouldnt be in the right order though

So this uprated TC... Is it not made out of chocolate like the originals ?
So it should last ?

The new one is made out of Dark Chocolate so hopefully with regular oil and filter changes it will last as long as I own the car (hopefully 4 - 5 years)

According to JPAT there are no "uprated" TC's available only new or recon - Introducing the story of JP (Automatic Transmissions) Ltd so far

dave thats cheap mine cost £2150 so far and is back in after only 5000 miles stripped down again with problems,personally i think once they have been in pieces they are never right again,its now on its 3rd valve block hopefully its ok,the original full recon box had very slight issues so a recon replacement valve block was purchased and it was worse than the 1st one, another was purchased from a different recon supplier and is being fitted as we speak.dont forget to replace new cooler and pipes aswell its a must imo good luck

Had the call off Nigel at VMTP this afternoon

Car all done and ready to collect

They have road tested car and put it back on ramp to check for leaks and spanner check etc

I have asked them to keep overnight and do another road test from cold in the morning - they agreed no probs

Will update once I get it back and drive it for myself
