wngrog - the ball on the R150F is removable. Just unscrew it and bolt it to Marlins bellhousing. from my understanding you will need to reuse a R-series fork in marlins bellhousing. I just got marlins bellhousing and haven't mocked everythign up yet, but I got all the parts in the garage.

RHG - Just get a W59 Bellhousing. that will adapt a 2/3rz to any W or G series tranny.

Wngrog - here is your answer to teh different R-series trannys. Bascially the longer input trannys require a spacer....

The 1 1/8" steel spacers are required if you are using a 2wd Supra turbo R154 or a 3.4 V6 2wd R150, or 4wd  R150F.
It is unfortunate that Toyota still uses the same R150 designation on the newer redesigned 3.4 trans that has an 1 1/8" longer input and matching longer release bearing.

This longer input gives more air space in the bellhousing resulting in greater cooling.

The 1 1/8" steel spacers are required if you plan on using the longer input transmission. The matching clutch release bearing must also be used.

Wngrog - I also had to look this up since I'm very close to bolting everything together, hopefully tonight!

....Complete Parts list for Marlin bellhousing as best as I can tell....

Marlin 2/3RZ to R-series tranny Bellhousing

No Spacer for short inputs: Turbo tranny R151 & V6 R150F
1 1/8" Spacer for long inputs: 2wd Supra turbo R154 or a 3.4 V6 2wd R150, or 4wd  R150F.

Heavy duty 12x1.25mm pivot ball found on all "R" transmissions.

Shift fork found on all "R" transmissions.

Fork Boot found on all "R", "W" or "G" series Toyota Trannys.

Rubber vent not required since its cast into belhousing

'96-'04 Tacoma lower dust shields and (4) bolts with 10x1.25mm threads.

The four original 12x1.25 x 60mm long W59 bellhousing to block.

The (9) W59 or R bellhousing to transmission bolts can be reused. <- (4) of my (4RnrRick) bolts were too long, so I had to find (4) shorter ones....

(2) dowel alignment pins for the bellhousing to tranny housing alignment - I reused the ones from the R-series tranny.

The factory 2RZ/3RZ backing plate, starter, flywheel, pressure plate, and clutch release bearing must also be reused. Although the longer input trannys may require a different clutch release bearing? ? ?

Clutch Slave Cylinder - Not sure but I think the W59 series for the Taco???

Not that I know of - I think you have to order the 1 1/8" spacer seperately... The person that took my order (I think Kyle) asked me what tranny I was planning on using.......

It depends of what transmission you will use:

Using this Transmission ........... Price
1986-87 R151F$399
1988-95 R150F$399
1996-04 R150F$499

The price difference for the 1996-04 R150F transmissions is for a required bellhousing extension kit due to the longer input shaft of this transmission.

Right awn man. I am still running a W56 in mine (at the time there was no bellhousing for the R-trans). Bevin already blew up his G52 behind a 2003 3RZ. His 5th gear was totally shot when we tore it down. He said that he is making better gas mileage with the R151F, which makes sense only if his trans was totally shot. Now I am wondering how my W56 is holding up, and if I could be running better with the R. If I swap over, it won't happen until fall-

Remember its not only the strength advantages, but if you use the R151F instead of a R150F, then you get a new lower 1st gear (4.31:1 vs 3.95:1). Bevin's Ultimate with 5.29s went from 223:1 to 245:1.

thanks for the info Mike. Ya i already have a r151 an duals in my runner now so i am really happy i can keep it in when i do the swap.

. Now I am wondering how my W56 is holding up, and if I could be running better with the R. If I swap over, it won't happen until fall-
and you have your 3rz super charged  :driving: :burnout:. I bet you would have blown up a G series trans a long time ago.

Only reason why I swapped mine W56 to R150F is because I had complete reverse gear failure (all three reverse gears), Forward gears where doing fine and this was the same tranny that was behind my 200HP 7MGE. but in doing so I lost a bit crawl ratio (3.95:1 vs 3.83:1) so now with 5.29s I'm at 216:1, but its really not that big of a difference from 223:1. IMO its not worth spending money on lower first gears from one of the other R trannyes..

Anyways - everything bolted right in for me and with my combination W56 to R150F+V6 tcase adapter - I didn't even have to change my T-case mount because everything was exactly the same length! Which also means my drivelines are the same length. Thanks for the R&D on that one.

Below is some contructive critism for you guys...

I do think the hole for the shifter fork boot in the bellhousing could be a bit bigger, both of my boots wouldn't fit quite right. Also I couldn't reuse all 9 of the bolts that secure the bellhousing to the tranny, 4 of mine where slightly too long for the blind taped holes in the tranny housing - so I had to get some shorter ones. I also was surprised at the thickness of the bellhousing - I would have thought it would have been thicker - might be nice to add some ribs to the casting....

Other than those minor comments - Nice product and nice fitment!

OK, turns out that I got the bellhousing for the 3.4 R150 and I have a 3.0 R150.

I take it all I have to do is knock the spacer off the adapter?

Do I need the dowels when I use just the bellhousing and not the spacer?

Finally, the bag of bolts in the kit....are they there becaouse of the spacer?

Yes, you need to use the dowel pins.

I got mine all bolted in today.  The hardest part was getting the dowel pins out that were there for the 3.4 spacer.  They were in there like a tick. 

All the fitment was perfect.

One thing though if anyone cares, the overall length from my old W56 with W59 bellhousing is 1/4" longer.

The reason I know this is my old crossmember was mounted to the lower tranny bolts and into the doubler. 

That said....can't wait for my 4 speed Atlas to show up!

More problems with my setup, the Altas kit does not work with the 3.0 R150...just the 3.4 R150. 

I had to snatch it all out and get a 3.4 tranny.

Now, I have spent all morning f-ing with it, just to read (missed it the first 75 times I read this thread) that I need the longer release bearing.

DAMN.  This is killing me.

More info later....

I really don't get it....the bellhousing I took off my 99 Tacoma R150 4x4 tranny was only 6 1/4" long.  Why would I need a spacer?

I tried it without the spacer and it would not work.

I am waiting on a clutch release bearing, so I was just messing around and tried it.  No go.

I measured the front output on my W56 and it was 5 1/4..the output on the R150 was the same.

Where is the extra 1 1/4" coming from?

It is the length of the input shaft, not the length of the housings. A 1996+ R150F has a longer bellhousing than a 1988-95 R150F.

Check out these pictures I snapped the other day :thumbs:

My tranny came out of a 1999 and a 3.4 V6 and the bellhousing is 6 1/4" long from the stock application.

Here are the steps I took:

I first got a 3.0 R150....the bellhousing I got from you guys had the spacer because I was planning on getting a Tacoma 5 speed.  Well, I failed to realize that the tail sections were completely different, so when I got the transmission all bolted up (without the spacer on the bellhousing), all worked well, but my Advance Adapters Tacoma/Atlas adapter would not work.

SOOOOO, I pulled the tranny, and swapped it at the wrecking yard for a Tacoma 5 speed.  I saw the donor, it was a 4x4 3.4 Taco.

Brought it home, mated it up to the Atlas to test fit the clocking.  So far, so good.

Then, I stuck the spacer back on the bellhousing, stabbed the transmission and the clutch relese bearing was just flopping around on the shaft....it was not hitting the fingers on the pressure plate.

Come back, read the thread again, and bingo, I see that the later R150 needs to use the longer clutch release bearing.

I ordered the part and am not waiting for it to come in.

Here are my questions...

1) I measured the bellhousing I took off the tranny I have and it was only 6 1/4" long.

2) Also, the input on this transmission is the same exact length as the input shaft on my W56 that I was running before (and that I have in my shop)

I am retarded...sorry.  My question reference the above, is where is this 7 1/2 in bellhousing I am supposed to have/need for this 3.4 r150?  Mine is 6 1/4 inches long.  The input shaft on the w56 and the R150 I have are the same length.  From reading all of this and the fact that with the w56 clutch release bearing wont engage leaves me confused.

With Marlin's help, I finally figured out what I have.....it is a 99 Tacoma 4x4 tranny....R150 with a short bellhousing like the old R150s out of the 3.0 trucks.

That was fun :screwy:

It is the length of the input shaft, not the length of the housings. A 1996+ R150F has a longer bellhousing than a 1988-95 R150F.

Check out these pictures I snapped the other day :thumbs:

BigMike,
In pics #2 and #3, what slave cylinder and throw out (clutch release) bearing are being used? R151F?

In pic #3 is that the '96-'04 Tacoma lower dust shields and (4) bolts with 10x1.25mm?

Thanks!

Marlin designed the bellhousing to be as much of a factory install as possible.

Slave Cylinder: Factory 3RZ (W59)
Release Bearing: Factory 3RZ (W59)
Fork: Factory R-series Fork (R150F, R151F)

The Dust shield is a custom piece that we include with the Bellhousing kit, you are correct about the bolts.

Once I get the bellhousing online for ordering, a picture will show what all is included in the kit. The dust shield is a custom part that is made for the bellhousing, and is only available through Marlin Crawler Inc.

Kinda...... I just reused the dust shield that came with my 3rz from a W59 bellhousing (2000 4wd Tacoma).
