24230682 vs 24230715: which one is left, and which one is right?

The two part numbers

Both are used on GM and Opel vehicles fitted with the 6T40 or 6T45 transmission, in the 2006–2013 catalogue range. The transmission code — not the model name — is what determines fitment. See how to verify below.

What we actually found in a supplier catalogue

While auditing a Chinese wholesale catalogue of roughly 2,800 sealing parts, we cross-checked the left/right designation on these two OE numbers against independent catalogue data. The result:

Four rows. Two OE numbers. The same catalogue contradicts itself on both of them.

We are not naming the supplier. The point is not that one company is careless — the point is that listing-title data is not a reliable source for left/right designation, and if you are sourcing from listing titles, you may be sourcing from data that has never been reconciled against a second source.

Why getting this wrong is expensive — and it is not the seal that costs you

An output shaft seal on a 6T40/6T45 is a low-value part. If the wrong side arrives, the loss is not the price of the seal.

The loss is that the transmission has to come out a second time. The workshop has already paid for the removal, the fluid, the bay time and the technician's hours. A part that costs a couple of dollars can write off a full day of shop capacity.

This is the single most expensive failure mode in this part number pair, and it is removed by one habit: write the side into the part number every time it is written down — not "24230682" alone, but "24230682 — RIGHT (RH)". Ask any supplier to do the same on the quote and on the packing list, and put it in writing before the goods move.

How to verify before you order

1. Ignore the listing title. Treat the seller's "left"/"right" wording as unverified until it is confirmed against a second source.
2. Confirm the transmission code first, not the model name. 6T40 and 6T45 are what matter here. Two cars with the same badge can carry different transmissions.
3. Ask the supplier to state the side in writing, on the quote and on the packing list. A supplier who will not put RH/LH on paper is telling you something.
4. If the vehicle is near a model-year boundary, send the VIN. Year ranges in catalogues are approximations of production reality, not the same thing.
5. Order both sides when the job allows it. On a transmission that is already out, the cost of carrying the second seal is far below the cost of a second removal.

What we do not claim here

Frequently asked

Is 24230682 left or right?

Right — RH, per multiple specialist transmission catalogues. No public GM side-assignment document was located.

Is 24230715 left or right?

Left — LH, per multiple specialist transmission catalogues. No public GM side-assignment document was located.

Are the two seals interchangeable?

No. They are side-specific. Fitting one in place of the other means removing the transmission again.

Do these fit both 6T40 and 6T45?

They are listed for GM / Opel vehicles fitted with either transmission in the 2006–2013 catalogue range. Confirm the transmission code on the specific vehicle before ordering.

Why do so many listings get the side wrong?

Listing titles are usually copied between sellers rather than verified against a primary source. Once an error enters that chain, it propagates.

Both numbers are in our GM 6T catalogue, listed with side, transmission code and exclusions.
