I'm sorry to hear about the issues you are having, and if we can help in any way, please feel free to call.
I have gone through our database with the information provided via email, and can not find anything using the supplied VIN.
I can not recall replacing any transmissions HDJ81s at all, so that also does not help with a search.
Rod bearings are replaced rather routinely, so I can't search using that information alone.
Actual failures of the 1HD-T are few and far between, and we have only had one come in for rebuilding to date, which we have just completed are in the process of installing gauges on (Oil Pressure, Transmission Temp, Pyro/EGTs).
We can supply new engine parts for these engines at reasonable prices, and in a timely manner. If you're looking to rebuild, we can help.
If you're looking for a used engine, I have one here with 175,686 Kms on it from a ~1991 that was a decent runner when removed.
