Speedometer crapped out after tranny swap
I converted the auto trans on my '75 to a super t-10 4-speed a little while ago, and now the speedometer doesn't work. It worked fine with the auto tranny.
I checked the cable with a drill motor and that test is good.
I pulled the speedometer cable housing from the transmission and can see the gear is in tact, and isn't chewed up- noticeably, at least.
What else might factor in with the speedometer not working besides the plastic gear?
If this helps, the speedometer worked sporadically right after the trans swap, now not at all.
Thanks

if everything forward of the transmission is working, then check the plastic gear on the output shaft of the transmission. maybe it's shewed up or the locking pin broke and not letting it spin with the output shaft.
also the plastic gear might be worn out out where the speedo cable goes into it

^ ^ ^ Thanks. I've been looking into that. It appears the problem is either the drive gear or the driven gear. If it's the drive gear, then the tail of the tranny has to come out, so I'm hoping it's the driven gear. Like YOU need me to tell you this ... haha!
If it ends up being the drive gear then I'll get the drive shaft u-joints changed out while it's down. I just hope I don't have to remove the entire trans to do this job.

Wish manufacturers wouldn't make gears out of plastic. It's not IF they will break, it is when they will break. But I guess if they only expect the cars themselves to live for just the warranty period, no biggee for them.

Speaking of plastic ...
On the starter motor on my son's 2011 Hyundai Sonata the lever that actuates the starter drive gear is ... you guessed it!
So I bought the part ($10.00) and repaired the starter, otherwise my son would have had a mechanic's bill of $500.00 +. Of course repair means replacing an otherwise perfectly good starter because of a plastic lever.
Oh, and this starter lever issue is well known, similar to the problem with the plastic pin in the steering column that is also known to crap out.
And neither has a recall attached.

We also have a 2013 Honda CR-V, which for us is a really great car! I was thinking about getting a newer one when this one's finally retired, but then I found out that the newer models use a CVT (read - SNOWMOBILE) transmission. Lighter weight and cheaper to build will have me looking elsewhere.........

I agree, but I must admit, that after reading more than one review on the CVT, I am impressed with the reliability stats on that tranny. Apparently, they've come a long way since their early Nissan days.

Yeah, I couldn't believe it when I read that the early C5 sway bar end links were made out of plastic....

My sway bar end links got replaced with metal ones when one of them failed.
It all comes down to better fuel mileage and cheaper to manufacture these days.
Never mind that the cost to repair is higher, the customer is paying that anyway.
