Can anyone recommend a place to get my gearbox and torque converter rebuilt?

Every time.

Don't know if it's one @Bemble rebuilds I've tagged him so he may respond.

Is it the box/torque convertor or something else like prop UJ's etc? Oil changed recently? Levels OK? Check the cheap stuff first.

DrTranny works wonders, two tubes.

I did the oil and filter a year or so back.
Ashcroft dont do the 6hp2 apparently.

Definitely NOT "Smart Reconditioning" of Sunbeam St. Wolverhampton.

Sounds like the voice of bad experience.

Nope, but I have read their "rave reviews".

It's only when I give it a bit of Welly with a trailer on. Can uj's make the car judder?

Yup!

I take it they will just appear to be loose/ have play when I inspect?

You will need to jack and support one side of the car so you can turn the props to check the uj`s

Is yours from one of the years that had a recall on front prop splines?

Good call,pity the op didn't provide full details of the car. perhaps the forum librarian can post photos, what do you think @brianp38dse

Ok heres the pic of the front diff recall

I'll have a look. It's a 2005 V8 with the Jag engine.

If it is tthe Jag V8 - I think the spline issue was resolved by then...

Has anyone rebuilt their own torque converter and gearbox?
Im tempted to buy secondhand, fit that, then rebuild my originals if its possible?
