Hilux RC60F Transmission swap

I see that you quoted my older post. Yes, when I wrote that one I was thinking of using all 6 gears, in which case I would not really want the 4.30s on that transmission meant for a diesel. For me I’d use 1-5 on 4.30s, or 1-6 on 4.88/5.29. Maybe skipping 1st occasionally on 4.88/5.29 depending on the situation, Aka starting downhill I wouldn’t bother with 1st.

 

I've recently been eyeing up this part of my project...

Everything is appart, just need to reassemble. The pump is in no way required, or any of the other tweaks... the input shaft is the largest part of the work.

I need to review the shift housing again, an internal part may(?) require swapping...will report back.

I don't forsee any major snags at this point... I'll be updating very shortly.

 

I do suspect the shift lever housing will need to be swapped, but from memory it can be done externally, not that it really matters if you're in there swapping the input shaft, haha.

To others discussing using this gear or that gear, etc., it's not possible without making a custom countershaft. Reverse, 1st, and 2nd gears are the same for all RC transmissions, and 3rd, 5th, 6th, and the reduction must be changed as a set.

The only possible gear ratio sets using off-the-shelf components are the the ones that come with the RC60, RC61, and RC62.

I’ll clarify since I was the one talking about gears. Not trying to custom home brew my own transmission with my own ratios I want, I was referring to how I would drive either transmission and what specific gear I’d use in a certain situation. I was just saying if I had the Hilux and 4.30s, I would not use 6th. That transmission has an ideal (to me anyways) 5th gear that would work well essentially driving as a 5 speed in my mind.

I am curious what you meant exactly in your post though. Are you saying the R-1-2 counter gears in all of the RCs are the same, and they come up with different ratios by changing the gears on the output shaft? I’m confused by when you say R-1-2 are all the same since the 60 has 4.78/2.42/1.44 ratios and the 62 has 3.98/2.02/1.32 ratios.

edit: I actually think rereading the post I know what you mean now. All the R-1-2 are the same and what makes the different ratios overall between the RC60F and RC62F are the front two gears on the input and counter shaft. This makes sense since the proportions between 4.78/2.42 are the same as 3.98/2.02.

 

Yeah you got it. The number of teeth on the R-1-2 gears are the same for all RC6x, but the reduction gear ratio is different between the RC60/61 and the RC62.

Only thing I would add is that since the RC6x is a tail set transmission, the reduction gearing is between the counter and output shaft, and not the input shaft like it would be in a conventional transmission.

Moving slowly, hit a small bump, so I had to order a 5" ID x 12" long piece of tubing. This will allow the hubs to be easily pressed off of the main shaft. Much of the main shaft and stack of gears will sit inside it while on the press.

 

I am just curious if either of you have a power flow diagram of the RC6x family of transmissions.

Thank you. That is an interesting use of the counter shaft and output shaft for gear arrangement. Makes sense too, makes it more compact.

 

Ok, does anyone around here have some experience with synchronizer design and materials? I need to know the intricacies of the blocker ring dog tooth count, as well as which carbon fiber facing is superior, the molded, or sheet type? There are a few variants floating around between the various applications for Toyota, Lexus, Porsche, and GM. I'll gather up some pictures to show off the types.

 

Does anyone happen to have info on the RC61F (gear ratios, swap to stock t-case, etc)? I have an 09 with the 1grfe and ra60f that crapped out on me. Am following the build others are doing with the RC62F, but saw the ratios on the RC60F in this thread and if the 61 is similar and would mate to the 1grfe that would be sick... otherwise I suppose I'll just stick with the current plan to do the RC62 swap. Thanks for all the info and advice given in this forum.

 

The RC61F has a different 5th gear(.826) when compared to the RC60F(.777). All other ratios/components are the same... no idea why.

 

Have we determined that the RC60F and RC61F are basically identical transmissions besides the 5th gear? I used that 33030-0KE40 part number and found it on toyotapartsdeal.com, a US based site. It says ships in a few days and that price is fair considering the RC60F I can only find at questionable overseas sites that I have trouble trusting.

If the input shaft we are using to convert for the 2GR would work on both the 60F and 61F, then this might make the 61F a very real swap for me.

Out the door total for me would be $3235.

Gear ratio wise, yes the 5th is the only difference.

 

Yeah, got that, mainly just want to make sure the input shaft that @Jowett is using for the 60 would also work on the 61.

The only other real thing to figure out is the shifter. I'm still not sure if I can remove the hilux extended shifter housing and just bolt mine from the 62 on.

@Jeff Lange, do you know the part numbers of those 2WD RC60 and RC61 that use the direct shifter? Any idea if those will just bolt in place of the extended shifter housing from the F 4WD models? Also, any idea if the shifter canes will pop into place interchangeably? If my RC62F shifter housing would not work on the 60/61, I'm wondering if I could remove my stick and install it into the 2WD direct housings from one of the other two.

I wish there was more info on these swaps!

 

I mean.... Most people just regear the diffs

 

Already doing that! The transmission would complement the regear really well.

 

While I have not attempted to bolt the shifter up, everything points to yes, it will bolt up with one part swap. All cases, gaskets, and rods share part numbers. However, the small cast lever inside the transmission - the part the shift lever inserts into, needs to swapped for the RC62 piece.

I’ll be surprised if they don’t cancel your order. Toyota will want a vin# for the Hilux along with documentation that shows it was legally imported in to the USA. With that said, maybe it will sneak through.

 

They might... They might not. Sometimes they don't seem to give a crap. For example, we've got an engine replacement happening here because somebody thought it was a bright idea to go to Valvoline for an oil change and now they need an engine... Toyota sent an engine for an SR5 which unfortunately does not have the hydraulic brake booster that is present on the off-road and pros. The truck needing an engine is an off-road. Had they done a VIN check they would have seen that.
