Manual transmission Fan Club and BS thread (All Generations Welcome)

Hmm, looked to me like the little boot on the slave cylinder was sealed all around--is it designed to be peeled back or popped out of place?

 

Hi there, I also have a ‘20 MT. There is another thread here with a TSB number related to this issue. That TSB only goes to 2019 MY (at least when I did it), but Toyota honored it. The replaced my assembly for free, and it has not came back since it was done 9 months ago.

 

Got 82 on mine, despite all of my off-road and towing abuse, it works great

 

Yeah, still works fine, no change in function, just the squeak bothers me.

 

Hard to find solid info on regearing a manual. Anyone have a link to a good thread? 4.88s or 5.29s?

I have a ‘16 sport with not a lot of weight currently. Tepui RTT is all. Eventually bumpers and a Leer cap. I currently have 285/75/16s but considering going skinnier because they are finally getting worn out.

So, not sure on tire size or gears. Persuade me. One thing that is for sure, I will not run 17s.

 

Considering stock is only medium performance and not really “wow”, I’d opt for 5.29s. 4.88s on 33’s gets you about back to stock if that’s what you’re after. For me 5.29 is a no brainer. Especially with you planning on more weight. Mpg will not be good no matter what way you go and it probably already isn’t good either.

if by skinnier you mean also downsizing to not as tall tires, then maybe 4.88 but to me that would depend on the size you’re planning on.

 

Yeah MPG sucks and I don’t expect it to be better nor do I care. I have another car for fuel mileage.

I honestly only want to rehear because I’m tired of the sluggish feel starting out in 1st. Reverse is near impossible if I’m starting on a hill. But thanks. Kind of leaning 5.29s anyway.

 

I hear ya, I’m not really a fan of the gearing in stock form, I’d really not like 33’s. I’m regearing to 5.29 soon and I only will have 31.5” tires, but I also am relatively determined to do the RC60F trans swap someday which has a taller highway gear. If that swap takes forever for me, I don’t mind revving higher in the meantime. If it doesn’t ever happen, I’m cool with that too. But if I had 33’s, I’d definitely do 5.29 for myself no question as a permanent setup on the stock trans.

 

I'm definitely following for your experience while I hang out on stock tires till my kids are older.

Kinda tempted to regear the '05 2wd first, add a locker and go 4.88 with the 5 speed transmission? Maybe too much there? Dunno. Not sure if I want it lifted or not but right now it has 1" of squat so maybe it's time to go high in the rear to compensate.

 

I really want to get myself some sort of go-pro or something so I can video the cluster and do some spirited driving before and after. The regear date is edging closer and closer (February) and I still have not really figured anything out. That would give people a better idea of what driving either is like.

I am on the stock size tires (265/65R17) so it is going to be a bit low at first. About 3000 @ 70. But, that is not the end goal, mostly just what I’m on. I don’t mind driving 70 at that rpm while I run out the tires. They aren’t worth enough to sell. If I can make the RC60F happen, I’d stay on the smaller tires because the 60’s OD2 is tall enough for me to run those IMO. Iffen the RC60 doesn’t work out, then worst case, I have basically limited myself to stock 5th gear forever. I’m ok with that, I already use 5th a lot of the time anyways. I still get 17-18 mpg in 5th at 70 and it’s not really better in 6th anyways so I’m cool with that. It will definitely be sporty.

A locker or even a torsen LSD would be nice. What was the stock axle ratio on that truck, and what’s the OD ratio or the trans model? Is that a 4 cyl or V6? I have an AX15 (made by Aisin, basically a brother to the old R150 with just barely different ratios) in my Jeep with the 4.0L straight 6 (torquey) and 4.88’s on 31.6’s. 0.79 OD. It’s a beast, lots of fun. About 2900 @ 70, which is a titch high but not really when the same Jeep could have rolled off the factory floor with a non-OD 3-speed auto. Those revved like 3200 at 70 from the factory. So I can pretty much justify any low gearing I want to and it’s still less than the stock auto would have been.

 

My '02 Tundra was stock 3.91 w LSD but 4 spd. I went up to 285/75R16's Cooper AT3 XLT's at 32.56 along with a regear to 4.56 w nitro LSD (torsen I think?) but with the v8 and how little I've driven, not sure I notice much change. Also AT so harder to tell. I'll give my feedback when I drive it north in less than 2 weeks, finally she's coming home, though highway isn't going to tell me too much. The thing I noticed the most the few times I drove it was the speedo being off, got a yellow box, haven't connected it yet, it's sitting in the cab somewhere (I hope) even though it has the harness.

The '05 Taco is 4.10 per Zuk with 8.4" and since it's 2wd prerunner it's a little tempting to toss in a locker and go bigger, but with only 5 gears and it being the best on gas, I am wary about trashing highway economy. But it's a 2 seater so maybe I DGAF about that and use it only for around town stuff? Dunno.

I'm somewhat interested in the trans swap if you prove it all out but not sure I want to do trans swap + regear the '16 since it's both my newest vehicle and the most obvious choice for kid hauling plus that's a lot of expense on parts which are only 6 years old. Much easier to swap out '02 and '05 parts, though Zuk said my gears and LSD looked super clean.

 

Yeah, an AT with decent power driving it can kind of gloss over gearing changes. The torque converter provides so much dampening and the trans shifts faster than it’s often hard to even feel the change until you really get on it and notice how much easier it goes then. And yeah yellow box should fix you up. No issues on a later Tacoma, that’s all wheel speed sensor driven data so gears don’t change it.

Hmm curious what ratios that trans has. I’d guess probably about 0.80 I’d say that’s the wrong truck for highway mileage cruising but I get it, it does the best, hard to not want to preserve that. 4.10 to 4.56 is not a massive difference so I wouldn’t do that. 4.88 would probably be good, but to know the rpm and such need to know more details.

I’m waiting on Brian to figure out the trans swap before I do it. I think it’s all good to go except maybe the shifter. It looks like you can just unbolt that shifter extension housing (from his pictures) and then bolt on the Tacoma shifter to that trans but I need that confirmed before I drop $4k on a trans and labor on the input shaft and whatnot. If it’s confirmed, then in a year or so I’d drop a work bonus on it and knock it out. And of course, I’d get the trans all built first and then just knock it out on a Saturday. That way my DD truck is not stuck in limbo unable to drive.

 

Yeah if it’s a go for you I’ll be tempted.

For the ‘05 I think these are the 5spd Mt ratios:

5 Speed Manual
1st= 3.95
2nd= 2.06
3rd= 1.44
4th= 1.00
5th= 0.81
R= 4.22

 

Looks like 265/70R16 or 265/65R17. Being a 4 cyl I think 4.88 would be pretty solid. 4 cyls are good to rev and they usually don’t suffer mpg horribly from it. The common Jeep regear mantra for 31’s with similar trans gearing (0.85 OD so slightly higher rpm) is 4.88. Considering your tires are about the same and it’s a revvy 4 cyl, I think 4.88 would be a nice improvement.

You could try driving in 4th on the highway now. That is higher rpm than you’d have in 5th on 4.88 by about 150 rpm. It’s something to get used to, seeing the tach higher and hearing a bit more engine noise, but power around town with lower gearing sure is fun.

 

Good idea. If I ever get it back from the shop I’ll try that out. I really screwed my self with the suspension plan.

 

17s offer a plethora of tire choices. 16s are well on their way out.

4.88 on 33s is a bit better than stock. 5.29 for the wow, and the wind up on the highway lol

5.29 and 31.5s..... boy howdy. That'll be a veritable go kart

 

It's just beginning

[Confession, I'm a huge fan of electric vehicles. Just realistic that they don't provide the same character and drama and not sure I want to see it faked]

 

Yeah I mostly consider 4.88/33 to be mostly equivalent to stock once you consider the extra weight and meat of handling a 33. It’s about 100 more rpm on the hwy which is probably about on par with feeling like stock after the heavier rubber. It might be slightly better than stock performance.

Lol that’s the goal!

In all honesty it actually should drive REALLY nicely. It will be a bit buzzy but I’m fine with that. Definitely won’t be for everyone. Hell, I see tons of people complain about how high their rpm is with 4.30s. I definitely can’t relate to that one, I hate sluggish performance and having to downshift all the time.

 

With my 33s and armor I pretty much only use 6th downhill on the highway. I don't mind having the revs up a bit.... This engine excels in the 3.5+ range

Still want 4.88s though

 

Maybe, maybe not. But I hate the look of the bigger wheel so I’ll stick with 16s just like I’ll be sticking with a manual forever.

Seems like I’ll be doing 5.29s eventually. Not anytime soon as I tuck my 3rd gen in the garage for the winter
