Manual Shift option wears out transmission

[toddarama]

Maybe compare the AMC 290 vs. 304 vs. 343 vs. 360 vs. 390 vs. 401
If you don't look at the displacement numbers cast on the block, they all look alike on the outside.
I love it when people ask "oh, is that a small block"? I answer - it's the only block. (well, sort of - you can't bore a 290 and make it a 343 or 360 - the cylinder wall thickness is the factor)

Bore and stroke both count right? Not that there aren't limits on both.

Limit on stroke is the head at the top of the cylinder and the bottom of the oil pan.
Limit on bore is the water jacket.

If we wanna go really off-base here, it may be hard to see, but there was a slight design change in the oil pan in the pic below to clear the rod bolts for a longer stroke - you can also see it in this block.

The TF998 transmission behind this engine worked fine on downshifts and manually shifting.........

I manually shift for ~70% of my driving. My JT has ~38K miles. No problems.

I’m planning on doing a pan drop and fill soon.

I manually shift because I prefer to keep the RPM up instead of letting the trans drop to 7th gear when I’m doing 43 mph lol

You can get 7th gear at 43 mph?? Amazing.

Brake pads: $26.40
Transmission: $3,755.00

I think everyone can relax that the transmission issues aren't related to shifting.
He's not had a single transmission hurt by it.
They all died from covid, bee stings, snake bites and other stuff - not by downshifting.

It's like the guy with a Wrangler who was saying he's now got problems with a second engine and everyone jumped all over various things including his driving, catch can, too much angle on the trails (he later said he was on the flat areas).
I finally got him to specific what "won't start" meant - he's got starter or electrical issues, nothing engine-wise and yet because his first engine literally blew with a hole in the side of the block, the owner and everyone else were jumping on this or that.

Same thing there as here - no dots to connect.

Dunno where you buy quality brake pads for 26 bucks.......

Certainly going through that many transmissions makes me think the owner is the problem. Couldn’t have gotten so many bad transmissions unless they were made concurrently on a Monday.

Monday is a myth. Look at numbers 2 and 3......
2 was DOA. Not owner problem. 3 had a whine from the beginning. 4 is fine.
Check out the German built transmission in the 4xe. Leaking for many owners. High rate of problems.

No one asked yet but how did OP get 4000k kms? That’s a lot of driving. Going through 4 transmission in 4 million kilometers is kinda reasonable.

It is a tale for the ages. The journal for it rivals the novel War and Peace.

That explains everything!

I'd be thrilled if any part of my truck lasted that long.
I'd be thrilled if I lasted long enough to drive it that far!
