YOUR EXPLANATION IS WRONG !! WHAT YOU POINTED OUT AS 4TH GEAR IS THE INPUT SHAFT THAT RUNS THE COUNTER SHAFT !! WHEN YOUR IN 4TH THE POWER RUNS DIRECTLY THROUGH THE MAIN SHAFT NOT USING ANY GEARS JUST THE DOGS COUPLING THE INPUT TO THE MAIN SHAFT. GET IT RIGHT!

Interesting seeing as 1kz and 1kd hiluxs had r series

Hey there, maybe you can help me since it looks like you have a alot of knowledge in the Toyota gearboxes. I am running a 200 series diesel 4.5 D-4D with the H150F gearbox. Now I ask myself wich of the plugs is the fill plug for fresh oil when doing the oil change. Is it the a bit higher one on the RH side, so same side as the drain plug or is it the bit lower one with the torx that is alone at the LH side? Bit confused and cant find any propper source online regarding this.

To be fair, it's not a gearbox issue per se, it's a drive style issue, most people don't addapt their driving when towing, but let's just say I've towed maximum permissible weights a fair amount and never killed a gearbox, Doesn't matter if it is on an old Ford Escort or a Land Rover, or Transit, you don't put excessive torque through the box in 5th as it's not ideal, however 4th is 1:1 and doesn't drive through the lay shaft, it does howver if too much torque is required it takes out the bearing in the back of the input shaft. as that is the stress point. The gearbox shown has had an oil starvation or shock load failure, if it was towing torque then it would also damage the initial lay shaft gear, what the presenter called 4th gear. for reference there is often a bearing in the centre plate so 5th is actually trapped between 2 bearings, that removes twist in the main shaft, so if the 1st gear thrust washer is broken, it suggests that it's not towing in 5th that killed the gearbox, but poor pullaways or lack of oil...

😮

So in 2017 Toyota upgraded the 2nd & 5th gear ratios in the H150 box. Do you do this mod?

Why 4th gear jump out or pull back after selecting

What transfer case comes behind the h trans? Also what’s involved in doing a “total spline” to the r series trans

Nice one

My 79 series Gearbox not engaging when sifting to all gears , it's engaging when the 4w gear is on Low 4, ???

Thanks for the tip guys!

Hi dear, Im thinking to swap my lc78 engine with the new land cruiser 300 series engine the f33a-ftv with same manual gearbox so is it doable? Thanks

Stand behind your product and give it a REAL warranty 100,000KM and 8 Years. I flog the piss out of my tuned V8 and tow in 5th gear. Has 160K on it and it only started changing gears nicely after 140K. Gotta use Castrol Syntrans 75/85 if you want it to last and change at least every 40K

Are there any 6speed gearboxes for theese engines?

Good content,which manual tranny can i use on my 91 fj80 3fe, manual swap.

I have a grandpa spec 80 series 1HZ with H150F and would love a taller 5th as we don't tow and vehicle is unmodified. Does 2800rpm at around 110kmh. Is that possible? What is the best swap or modification for this?

Iv never regretted buy quality

I need help my 78 Toyota land cruiser gear box got problem on 5th gear so can you gave some idea my dear

ive havea 78 series since 2004 and have had no problem !!!

You're a little unclear here, as collapsable spacers are NOT inherently more likely to wear bearings sooner than solid IF SET RIGHT and will not alter the pinion depth any more than a solid would when wearing. None of them can "un-crush" or re-tighten to adjust for bearing wear so when a tapered roller wears, provided it was never over-preloaded, it wears the same, pinion depth changes the same and if it were to wear enough to come loose and have float, it's also the same result. Diffs are NOT "doomed" with a collapsable spacer at all, it's simply easier, less complex and harder to get wrong with a solid. All of that equals cost and time, so is a no-brainer.

Nice details explained. Good job guys

I am a victim of the R151F gearbox with its weak 5th gear( which blew up ) and the gearbox to transfer case connecting shaft with its spline stripping problem in my old troopy…. $3300 for a new gearbox and $350 for the upgraded connecting shaft…… was still all good when I sold it. Loved my troopy.

Will these fit a 76 series?

But when I have towed on the highway in 4th once I get just over 80 she wants to go to 5th coz she will start reving to high?? So when towing do we need to just only do 80/85 in 4th in a 1hz 😅

How do i get one installed in the US?

Jackie your a legend 🤝

Best thing I ever did was put a towpack in my HDJ 👌🏻 Love showing it off and using less fuel than everyone else’s 79 😝

Does my land cruiser 105 with 1hz non turbo engine have the r151f gearbox ? I do mostly city driving with loaded trunk. Maybe a lil towing. Should I be worried about the gearbox ?

I’ve find towing anything to be shit

Gearbox dismantle

How much does the gearbox upgrade cost for the smaller H151 box? I tow a bit. Though careful to load the 5th gear to much.

Excellent

Hola , la caja h150f funciona bien en un motor 1hdt ?

It must be bad drivers that have issues with the R series mines got 400 tho ks on it running 35s on 18psi boost runs fine .

Do they have the same bell housing bolt pattern

First gee ahh and second gee ahh, then third gee ahh is hee ahh. Fourth gee ahh and ultimately fifth gee ahh

Super bien 👍👍👌👍👌

Ive started doing my own research on a new Gearbox for my 80 GX 4.2HZ And … I am so impressed with this build. I only wish to buy it from you as I am in South Africa

The new Landcruiser 76 wagon (1hz V6 diésel) (2021) Equip R151 or R150?

can the ute carry 4 tonne load?

Brian, I work for an international relief organization and we are experiencing serious issues with our gearboxes from HZJ79, red cross model. The gearboxes are breaking to the rate of consumable items. the drivers are very experienced with the terrain and 4X4 Toyota vehicles. We are really struggling to understand the problem...have you ever experienced or heard about something similar...please advise

80/100/105 series 1hz's had the h150 1hd and fz engines had the h151 1HZ's never had the r151 unless they came in the very late 79s, r151's were fitted to vdj79s only (in the landcruiser range) please get your info correct

Thank you! Excellent explanation. Excellent recommendation! Much appreciated !!! God bless !!

I drive a 2021 V8 diesel but i feel that it needs a sixth. Would your gearbox work?

Can you fit a sixth gear i to that box?

Hello, write me please, that the name of transmission and that the car use this transmission?

Is the 80 series turbo box able to fitted into a 100 series NA? I know the input shafts are different as are the gear lever position

Hi, I am Graeme John Eddington. Following is my KZbin post of my Multi-speed transmission I have called: "Opposing Torque Dynamic Clutch" which is a type of Infinitely Variable Transmission (IVT) which I believe is ideal for your current applications. Australian Patent Number: 2020201132. Please log on to my KZbin video: kzbin.info/www/bejne/iXKmdX5ubrpqhq8 In summary: It is a Compound Planetary System with two inputs from two separate electric motors. Motor 1 tries to rotate the carrier counter-clockwise and Motor 2 tries to rotate the carrier clockwise. The ratio, acceleration and speed of the vehicle is controlled by the amount and proportion of power/torque from the two motors. In addition the ratio of the transmission is affected by the speed and load of the vehicle. So, with the aid of speed sensors on all the components of the transmission, the speed of the vehicle, position of the accelerator and a kick-down switch - all that is needed to control the whole system is a computer. There is no actual gear selector for the driver to operate, however a manual mode would be appropriate where the driver has a 'balance' control knob that manually controls the proportion of power/torque to each motor and therefore can choose any ratio desired for the driving situation. An added enhancement could be added to the transmission by having a traditional planetary overdrive attached to each of the motors to enhance the rev range of each motor. This would enable the provision of extra modes like economy mode/sports mode and improve the kick-down mode by inputting more revs when the gearbox is in an extremely low ratio during kick-down operation. Having this type of transmission would improve acceleration and range of the vehicle allowing for a smaller battery pack/lighter weight leading to cost savings and simpler manufacturing.

What about my 94 Nissan civilian bus?
