Unfortunately I think your right I think. You can bring them the printout of the various gear calculations provided in the thread. I doubt they'll take this as cannon.I don't feel it's worth my time to have any more dealings with the repair shop. That renders moot whether they are not capable, or acting fraudulently, or both.
Counting teeth on the drive gear and the driven gear is part of what I am planning to ask the new Honda specialist. I didn't know the teeth are visible by just removing the casing. That definitely simplifies the task.If your willing to get a trustworthy shop to take the tranny out you can whip the casing off and count the teeth on the crown wheel and teeth on the countershaft and divide them. This will save the hassle of pulling the gears off the counter shaft and searching for part numbers.
Yeah when you whip off the case essentially you'll have the back of the crown rear fully visible as the diff will be sitting face down pointing toward the engine.
The teeth on the lay shaft that form the pinion gear will be a little more awkward to see but a little dab of gear marking compound on one tooth will make it easier.
This is excellent information but beyond changing engine oil & filter and cleaning spark plugs, I haven't done any work on the cars that I have owned over the years.The other thing to note is sealant between the bell housing and case.
If your tranny was built it could have non oem coloured sealant.
Hondas ive worked on it is normally black or opaque coloured sealent.
If it looks oem and its durty and grimey it'll be a dead giveaway that it's just a replacement unit.
How do I find out what is the original factory installed transmission number?Also, the transmission number would be different, or look like its been tampered with if they swapped it over.
(to the OP, its easily visible in the engine bay)
I tried that in the thread, the numbers don't coincide with the chassis vin. Not sure of what else or where this information could be got. Maybe a Honda dealer may be able to tell you.This is excellent information but beyond changing engine oil & filter and cleaning spark plugs, I haven't done any work on the cars that I have owned over the years.
I don't think I have enough experience (and possibly the tools) to follow through with your suggestions.
I can ask the Honda specialist if their technician can do these inspections.
