6th Gear Grind & Replaced Transmission

[Bonburner]

I already talked with the scion/toyota reps of the district and they told me it was out of good courtesy.

According to their break down there was no sign of abuse/racing - to which I never did anyways.

Interesting Side note from this transmission to my first:
1 - 2 drops more RPM than my first.
3-4 less rpm drop almost feels like 300 rpm.

another note - I feel like I can feel synchros lining up before I shift in .. odd lol


ive been debating double clutching but still not sure if I should bother lol

Don't double clutch..its bad for the car

Can u explain why its bad? I thought double clutching would help reduce strain on synchros

Well i goggled if double clutching was good or bad and alot of forums say that its not good and strains the transmission more than without double clutching.

Ill try and find the link and post it up here for you

Well I double clutch on downshifts (only when skipping gears though) everyday so I guess I'll let you guys know if I blow up my transmission. So far 15 months and 20k miles, no problems. I don't think its bad

Just reading this thread is pissing me off. The transmissions should be engineered well enough to handle much more abuse than a normal person could exact on it. I'm not talking about severe abuse, but normal shifting. I also consider skip shifting to fall within normal operation. These cars are ALL in their warranty periods. Toyota should GLADLY fix or replace any of these faulty transmissions without the BS. I understand what Dezoris is saying, but I'll be damned if I'm going to drive "cautiously"in case I hurt the car. Sorry for the rant.

This is typical warranty BS friend. I'm lucky to be able to take care of my car without worrying about warranties and dealerships. I've known many assholes (service advisors) at dealerships. They are not on your side. The marketing material is splendid though. A real treat.

Edit: I have the 6-5 grind. I have learned that if I shift real slow and just let it slip in, she doesn't grind. Any kind of quick shift.. No bueno.

In my 12.5 year ownership of my high revving 6sp celica I have often skipped gears especially from 4th to 6th. The car recently clocked over 320K's & the box is working just fine. My 86 6sp is not far from 10K and it too is just fine, except for the cold start grind from 1st-2nd & 2nd-3rd on occasions (no adjustment or fluid change yet).

Sure maybe double clutching might put a little more wear on the clutch parts, but it's easier on the transmission in certain situations. I usually only double clutch when I'm going into first when I'm moving and going under 10 mph.

Yeah i do it also only when i have too

I meant if you do it all the time then it might cause more wear in a long run

If anyone is telling you that Double Clutching is harder on the transmission vs regular shifting, they probably need to wear a helmet before they leave the house.

Double Clutching is quite literally syncing the 2 shafts without having to use the synchro to do it. When you double clutch your synchros do almost no work.


Edit: that civicforum link is specifically asking about the clutch/engine. Double clutching means you are pressing on the clutch pedal more often but usually when a double clutch is performed so is a rev match. No extra wear or stress occurs on the engine (probably less due to rev match) and the clutch is doing a negligible amount of extra work. The only thing that's actually getting more use is the throwout bearing. Reading that thread cost me 2 IQ points. I feel dumber after reading it.

Wise words.

how does double shifting hurt the transmission .. it makes everything easier - just minimal increased stress on the clutch flywheel and bearings ..

the first transmission was almost like this .. but then it got to the point where even slow shifting Could grind - take this as a yellow flag imo, the dealer's tech told me the same thing and I wasn't satisfied with his response of slower shifting. I already Am shifting pretty darn slow - this is a track designed (? not sure anymore) car I don't understand why I'm expected to drive it like a '87 toyota pick up.

and I have to agree there is a level of tolerance to be expected when you're building a commercial car to be sold worldwide

Reviving this thread. I seem to have a 6th gear grind too and might need to take it in to get it looked at.

Any advice? I know I'll need to flash back to stock tune, but do I need to worry about removing the headers and catback before I go in? (the only performance mods I have with OFT)
