Gear lash? Normal?

[justpez]

1990 Toyota FJ62. Factory 4 Speed Automatic.

So... Here is the question. Customer is stating he does not like this little bit of a tick/clunk noise when going into gear... Especially from reverse to drive. This is the only automatic we have seen in a 40/60 in years. None of can say conclusively that its not "normal"

I am really scared that dismantling this and rebuilding it will result in no difference. Thus a giant time suck.

Thoughts? Advice? Memes?

Thanks!

It's very common for sure...
Great posts in this forum about it.
If I make sure I hit all the grease zerks on the drive shaft + hit the brakes firmly while I shift, the clunk is pretty much not there.

But yeah a lot of 62's have worn down output shafts
Here is a possible solution:
McNamara Gear for FJ62 Clunk

Thanks. I am leaning towards leaving it alone... Especially after reading this. But its not my decision ultimately. Customer is always right?

Yeah.. I'm sure others will chime in here, but if you do a little bit of searching on mud you'll find a ton of info on this issue.

It all depends on how bad it is and what the customer wants/uses it for. If it's really bad it could be something that at a certain point completely fails/strips and then you're in pretty big trouble if traveling remote.

You can mitigate wear quite a bit by doing what I described above.
All depends on priorities and budget right.

If I'm idling high because of my AC being on or something, going between D & R can cause a pretty severe jolt in mine.

It's universal and due to wear on the the output shaft/input gear splines.

"They all do it"

Fix is as above. If I still had the autobox, I would have done the McNamara gear as prophylaxis.
