Bentley Turbo R auto-box service parts

[RB CV8]

I intend to have a fluid and filter change on the gearbox of my 1996 Turbo R. I thought I would see what options I have in terms of the filter and sump gasket as the cost from the specialists seemed a little high given that it is a US GM gearbox that, if I am correct, is used on a number of hefty Chevrolets, the Hummer and Cadillac Escalade.

As Xtriple129 has stated on another thread, a Bentley label does add a fair few shillings to the price tags of relatively common parts.

There are suppliers in the US that can supply what appear to be the correct bits for absolute peanuts in comparison with the UK RR/Bentley specialists. Interestingly, one of them, a GM parts specialist, even shows the same photo's on their website as a well-known UK firm. I have only found one so far that shows a "Rolls-Royce" listing, most listings being under the transmission type. There seem to be a few firms over here that list the right bits at fairly reasonable cost too.

Before I buy any parts from anyone, I thought I'd ask on here whether any fellow owners have purchased similar items and if they have any particular recommendations, either in the UK or over the pond.

Many thanks.

Whether or not the Bentley 'box is 100% as it comes out of the crate from GM I cannot say, though I'd suspect any changes are more likely to be to the electronics than the hardware. The relatively reasonable cost of a complete replacement gearbox does not suggest much Bentley input!

I am confident that the filter is a standard Delco item and available for pennies. I have not found a gasket under the part number that I would expect having looked at the FS website, but I don't think that will be an issue either.

I'm happy to report back on what I opt to do once the beast is out of hibernation.
