When I designed this new bellhousing, I took the opportunity to incorporate new features and improvements.

Because it can only be bolted to a "R" series transmission (large 9 bolt pattern), it will use the same heavy duty 12x1.25mm pivot ball and matching fork found on all "R" transmissions.

These parts are factory on all '86-'87 R151F 22R turbos, and '88-'95 3.0 V6 and '96-'04 3.4 V6's.

All other transmissions, including the W59, uses a smaller, lighter duty 10x1.25mm pivot ball and matching fork. These parts will not work with the new bellhousing.

The fork boot is the same and can be used over or installed as new.

The W59 bellhousing features two rubber air vents whereas my new design has the 3.4 V6 cast-in-place air vents.

There are two lower dust shields available for the 2RZ/3RZ bellhousing. '94-'98 T100 and '96-'04 Tacoma. Both use different bolt patterns and have pass thru bolt holes. The new bellhousing uses the more common Tacoma pattern and has four 10x1.25mm threads.

This lower dust shield kit including four attaching bolts, will be available at an additional cost if needed. Your orginal Tacoma style plate may also be reused.

The four original 12x1.25 x 60mm long W59 bellhousing to block, and the nine W59 or R bellhousing to transmission bolts can be reused.

The factory 2RZ/3RZ backing plate, starter, flywheel, pressure plate, and release bearing must also be reused.

The bellhousing is 6 7/8" long, same as the original W59 and weighs 10 lbs.

The cost of the bellhousing is $399.00. However, thru the end of this year, it will be featured at the introductory price of $349.00.

A complete list of options to fit your needs will be available including bolts, pivot, fork, fork boot, dust shield, and a bellhousing extension kit to adapt the '96 and newer 3.4V6 R150F with the longer input shaft to your 2RZ/3RZ engine.

Bellhousings are in stock now with the lower dust shield kits (which can be added later) due in two weeks.

I was only trying to answer questions.....

A transmission length chart along with shifter handle placements will be posted next.

Marlin - That sounds great! I did however refine a couple of my questions.

What is the length comparision between the following options. I'm more concerned with driveshaft lengths since since I would be converting from an existing W series to R series tranny.

1) 2/3rz + W59 bell housing + W56 + Marlin Dual Ultimate gear drive T-case.

2) 2/3rz + Marlin RZ to R Bellhousing + R151F + Marlin Dual ultimate gear drive T-case.

3) 2/3rz + Marlin RZ to R Bellhousing + R150F + Marlin V6 adpater (30-4GT) + Marlin Dual ultimate gear drive T-case.

Thanks......

BTW - what you calling the new bell housing - I suggest R2Z or RZR Bellhousing. What ever you call it, its TITS....  :wink2:

Marlin - I got one more question.....

Whats the strength comparisions between say the L vs G vs W vs R series trannies? If your unsure - how about a comparision between the diameter of the mainshafts or bearings sizes or inheirent flaws of each tranny?

Im I reading the chart correctly?

That shows OEM lenghts.

So Marlin sez the new bell hosuing is 6 7/8"

Reading the chart, Im interested in a W56 B to a new setup...

That implies that the shift handle will move "back" by about 4/8" or 1/2"...
yeah yeah - still IFS...

Hey Marlin,
     What exactly is the "bellhousing extension kit" for the 96 and later R series trannies?  Is that a spacer to space it back?  Any pics?

Yeah I've considered that option, but I think in the long run I would regret not upgrading to a w56 or even W56HD. This is all far down the line though, lots of mods have higher priority  :).

Oh sorry for the hijack, I'll stop now  :hammerhead:

Just a note for us people with short wheelbases.

Stock G52/G54 (84-87 22R Carb) 6 3/8” 19” 23 ½” 25 ½”

G52/G54 with a L52 tailshaft and custom tailshaft housing would be 20 1/2"

The down side here is that the tailshaft housing has to be custom made along with extensive shift rail modifacations.

This modifacation has been in my project for the last two years without a problem.

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.

Unfortionately I could not find a Turbo tranny around my area for a decent price so I just decided to do a full rebuild on my W56. Just got off the phone with Marlin Inc and ordered a Full rebuild kit....

What about a bellhousing to adapt a 7MGTE Supra motor to an R series tranny. I think you could sell as many of those as you will of this 3RZ adapter (which I hope you sell many of).

And what about an adapter to mount an RF1A transfercase on the back of the 6speed RA60 tranny from the 2005+ Tacomas? -- Matt

Matt,

As you are aware I'm sure, the 7M-GTE came equipped with the 2WD R154 5-speed transmission, but unfortunately it has a longer input shaft than the 4WD versions.

At this time we have no plans on making a bellhousing for the old 'M' engines.

I have no comment regarding the RA60 adapter.

R150 (96-04 3.4 V6)7 3/8”23”--26 1/8”

Hey guys,

I'm investigating options for transmissions in my 2001 Regular cab Tacoma 4x4 because I have what I believe to be a rapidly deteriorating bearing somewhere in my current W59 transmission.  I'm doing the research to see how feasible it is to swap in a R150F from a 96-04 3.4 V6 Truck into mine, since these W59 transmissions seem to have a lot of problems and appear to be the weakest critical link in the 3RZ drivetrain.  I see that you guys have this new Marlin bellhousing which would greatly facilitate this type of project.

Some posts I've read said that the output shaft from my current W59 transmission is splined differently than the R150F transmission, yet I also read in a different post that the same transfer case is used in both the 4-cyl and 6-cyl Tacomas as well as the Tundras.... and I'm not sure what to make of that as far as compatibility with the R150F transmission and my existing transfer case.

Based on th measurements that you guys were kind enough to post(assuming I'm reading and interpreting them right), it looks like the difference between the R150F transmission/transfer case when mated to your new Bellhousing in comparison to the OEM W59 setup is very minimal(1/8" to 1/4") in terms of shift lever location and total length of the whole tranny(I'm guessing this is a small enough difference to be absorbed by the compressible driveshafts).  Besides using your new RZ-Engine to R-Series Transmission bellhousing, what other modifications to a truck such as mine(if any) and additional parts would be necessary to make this work?  Are there any other additional considerations that might not be essential to making this work, but would make things work better(more aggressive clutch to facilitate heavier transmission and potential increased parasitic drivetrain loss when starting vehicle from a stop and also the slightly taller first and second gear of the R150, etc)?

My main concerns are to find out if the R150 is compatible with the current OEM chain-driven transfer case, and if there needs to be any changes made to the transmission mounting points and center support, as well as compatibility with the existing driveshafts, and the electric components such as the speed sensor and reverse sensor.

If you guys know and could post up some conclusive info on exactly what needs to be done to tie together a whole project like this, I think it would definitely help bolster consumer interest in your new bellhousing as well as rebuilt Marlin R150 transmissions for all those people like me who might be in the market for a tranmission replacement and see it as a worthwhile investment to spend a bit more money and seek an upgrade while we're at it.

Hey Guys,

I have one of these coming right now.  I bought the one for an R150 transmission, but no one asked when I bought it if it was a 3.0 R150 or a 3.4 R150.  From what I read, there is a difference.  Do the spacers come either way and you use them or not?

Also, the fork and the ball.....is the ball part of the old bellhousing.  I am getting an R150 from a wrecking year locally, do I need to ask them to include the bellhousing on the tranny so I can swip the ball and the fork to make it work?

I can reuse my old throwout bearing that was with my 3RZ/W56 setup, right?

So I have a w56 with my 22re in the 89 pickup. In order to swap over to a 3rz and use this bellhousing I need to get a r150? Damnit how bout a 3RZ to W series transmission! That would make my life much simpler since I have a Marlin W56HD in there right now that still has plenty of life to it.
