I can't see a sticker in that location. I remember there used to be one in the factory tranny.

In my case the invoice notes a honed unit but the sticker on the trans says otherwise. The dealer says they don't always remove the old tags. Some rebuilt trans will have no tags, some old tags, possibly some have a new tag indicating the rebuilt trans has a honed or non honed unit. After it comes out of the shipping box its anybodies guess what it is? You would think they would tag the unit to identify it. Paco

Check the 2nd photo of #978. The sticker contains the part number and the serial number. Just below the part number 30510-4H202-84 is the serial number (for example, 12HL-0390P). The serial number is the one engraved on the tranny housing.

Hi Revved4, Thanks for pointing out the photo. The identifying sticker is attached to the torque converter and would not be visible once the unit is installed. I knew it had to be identified somewhere on the unit despite the dealers claim to the contrary. Paco

Paco,

So what did you find out? Did the serial number on the housing match the serial number in the sticker/workorder sheet?

[pacopena]

Hi Revved4,
The sticker on the case itself appears to be from when the case was a new unit. The workorder only shows a part number not a serial number. The truth of the matter is likely on the torque converter which wouldnt be seen until the transaxle gets dropped. It may simply be a defective rebuild.

Paco,

I'm actually referring to the serial number etched outside the housing. This MUST match the serial number on the tranny sticker otherwise it's amiss.

Yesterday, I took my 2010 v6 with 50k in to fix the whinning, before my warranty is over. The service adviser(sa), at the beginning said they would charge $59.99 for diagnostic fee and reimburse if they fix it under warranty. I said 'nonsense' and insisted to have a mechanic to drive with me. So sa went back to garage and when he came back, he said that mechanic already knew about the whinning and right away he
started making the paper work. I asked if they can skip the stage I and order the tranny right away, and he said they had to follow the tsb.
And they knew the stage I would not fix anything. I guess they make money either way. Maybe they make more money doing 2 jobs for one issue.lol.
Hope they fix it correctly. Also they gave me a corolla loaner, since it might take
couple of days to fix.( I guess he was talking about stage I or do they already have a tranny in stock?)

Hi Revved4,
The only sticker visible on the trans is the original, pre-rebuild sticker. The serial number originally stamped into the case does match the original sticker. My issue was that there is no sticker or tag visible that indicated the unit was one with the honed gear set. I have about a year left on the lease. If it gets bad it will go back for another trans. If it hangs in there till the end its Toyota's problem when they sell it off.

I got my car back and the noise is gone !
It only took 3 days to do the job. I think they never did stage I,
because on my invoice, only list the tranny change and couple of
recall lists. BTW invoice shows 30510-4H190-84, so it is correct tranny, I guess.
Anyway, I am happy camper now. Complements to my dealer.
