Showerthought: My manual transmission felt like an old friend until I drove a rental CVT last week

I spent 3 years daily driving a 5-speed Honda, then got a Nissan Versa loaner when my car was in the shop. The whole time I was shifting with my left foot on the floor and it just felt wrong, made me realize how much I take clutch feel for granted. Anybody else get thrown off by a different transmission after years of one style?

I keep seeing people on here recommending synthetic gear oil for old manual transmissions that were designed for 80w90, but is that really a good idea?

My '89 Toyota pickup with 240k miles started grinding 3rd gear after I switched to synthetic GL-4 like everyone suggested, and when I drained it after 2k miles the old brass syncros looked more worn than any dino oil change I've done over 15 years, so should we be sticking with the old stuff for high-mileage boxes or are these just isolated failures?

Switched to synthetic transmission fluid in my 2015 Accord and the difference was immediate

Debate: Was it worth spending $200 on a fancy shift knob or should I have stuck with stock?

Switched to synthetic blend after 10 years of full synthetic and my engine runs quieter now

I think engine oil change intervals are way too short for modern synthetic oils.

Figured out why my auto transmission was slipping after 3 shop visits

Bought a "heavy duty" transmission cooler for my truck and it was a total dud

Can we talk about the guy at my shop who insisted synthetic oil in a 1995 Civic was a waste of money

That moment in Denver when I realized my clutch was slipping on I-70

Back in 2018 at a salvage yard in Nebraska, saw a guy swap a transmission in under 2 hours with just a floor jack and some chain.

Spent $40 on a magnetic drain plug and it caught a chunk of metal

TIL you can spend 4 hours chasing a coolant leak that's just a loose hose clamp on the lower radiator hose

Warning: My alternator died on I-35 in Austin at rush hour last Friday

Picked a used Snap-On box over a new Husky one and it was the right call for sure

Bought a cheap torque wrench from Harbor Freight and figured it would break after a month

My buddy's transmission swap story finally clicked for me

My $15 heat gun made removing old auto decals actually doable

Snapped a timing chain on my 2015 Ford Focus at 87k miles - was I supposed to replace it earlier?

Chat with a machinist made me rethink my tool storage

The worst road trip I ever took in my old Subaru

Hot take: the guy who showed me a trick for cleaning valve covers

Had a customer tell me my clutch adjustments were way off after 12 years

Finally got my torque wrench calibration spot on after 3 tries

Hit 5,000 miles on my truck and realized I should've checked the transmission fluid at 3k
