Isn't a starter for a 4bt a 24 volt or a 12?

Swap to a 4BT diesel in the future? Most likely.

Subscribed! I am looking at dropping a 4bt into my '02 TJ next summer, and had many questions that you're covering! Any reason you decided to go automatic instead of manual?

GREAT question as i gave up a perfectly good borg warner T19 that came with the motor and i am already set up for a manual trans. It was quite the struggle to make the call to go auto but here are the pro's that have me excited:

No riding the clutch on rough trails, no worrying about keeping the number of shifts low when riding through water that is trans-high, and most importantly... "set it and forget it" crawling rather than the constant gas bump and clutch slip.

My 4 banger was the 5 speed manual and even with the terra low gears in my NP231 i would lug the motor down sometimes and have to bump the clutch in or give it some gas and let the clutch slip. I am a big fan of manual transmissions, I just came to a cross roads of sticking with it or attemping the switch and well... a $200 700R4 on the internet was too appealing to pass up.

Another thing to think about... the borg warner T19 had no overdrive. 4th gear was just 1:1 which meant a low revving 4BT + 4.88 gears + 37" tires = good luck breaking 60 mph without over revving the motor. I highly advise those with higher gearing to run a gear calculator. With the Turbo 700's .72 4th gear I SHOULD be able to cruise on the highway at 70MPH (SCARY!) at approximately 2200RPM with room to spare if i need to pass a good ol florida grams and gramps doing 60 in the right hand lane.

For off road use, the 1st gear on the Turbo 700 is quite low which if my calculations are correct, it should crawl like no ones job.

A trans or diesel expert might chime in here and say "hey! bad transmission choice!" well you sir... i addressed you too. It is rare to find a turbo 700 behind a 4BT and even more rare to find an expert that would recommend it. However, I lucked out on finding the trans and also lucked out on picking up the adapter plate from the guy who sold me the 4BT in the first place. The selling points for me that I made the right choice are as follows:
1. I had the trans completely gutted and rebuilt top to bottom with all top of the line parts and upgrades such as corvette servo, heavy duty sun shells, all new planetary gears, 23 spline shaft, diesel torque converter, etc.
2. The 4BT guy that i also bought the adapter from said that the adapter was previously used to mate a 700R4 behind the 4BT and survived very well.
3. I have an amazing transmission expert who is going to help me tune the trans for smooth shifts, correct kick down cable alignment, etc. when she is up and running.
4. A common failure is that the motor running so low on RPMs over time heats up the trans fluid and struggles to hold trans pressure. To address the trans temp i got the biggest trans cooler ebay had to offer and a 3 core radiator that has ports to run the trans cooler lines also through the radiator so i get double cooling. She should run at optimal temps even on a good ol cook-an-egg-on-the-pavement Florida afternoon.

Could I have done the tried and true NV4500? Yes. But, I want to give an auto a try and why not see if the under dog turbo 700 can come out on top and live a healthy life behind my already uncommon drive train.

Time for some updates and more photos... For starters, THE MOTOR IS IN!!!


One more photo for good measure:


Here is a bit of a zoom out, this side of the garage is an absolute mess:


And the transmission is all in and rebuilt!


Some better looks at the transmission, I had to get a spacer plate (mid motor mount plate to keep the torque converter from binding on the flex plate. Took it to my favorite machine shop to have them modify the mid motor mount plate to remove the excess.):

as you can see, all of the remaining red under the hood is now black, the difference is amazing... so glad all of the red is finally gone!


For gauges, this is what i went with:
6 Gauge Set with Senders Speedo Tacho Oil Temp Fuel Volt Black Chrome Blue LED | eBay

Here are the replacement dash pieces that convert the dash "Bezels" into dash "clusters" that will accept the gauge set above or any other gauges you can think of that are standard diameter.
Autometer Dash Cluster Bezel 87 94 95 Jeep Wrangler YJ | eBay
Autometer Dual Gauge Cluster Bezel Jeep Wrangler YJ | eBay

Here is how it all came out:

This was just a test fitment, I have some plastics trimming to do. For about $60 per gauge pod you cant expect perfection.

So without a need for the idiot light cluster anymore, what should i fill that hole in with?? Why my ARB locker switches of course!! Bought a sheet of ABS plastic of amazon and cut it to fit:

It isnt perfect, but good enough for me. Gives it character i think.

If i ever have to pull the dash for some reason, i wanted to know that I didnt have to undo every wire on the back of the pods so I bought 2 trailer wiring plug sets from advance auto parts and spliced them in here to easily disconnect all 5 pods with 2 water "resistant" connectors.


Here is a not-so-great photo of the tach and speedo gauges in. Again, had to do some plastic trimming. Oddly, the gauges were just too large to fit so i took some sandpaper to the wholes and scrubbed off a bit of extra plastic on the gauge pod.

if anyone wants to give a turbo 700 trans a go as well, here is the MONSTER transmission cooler that will be mounted to the front clip. If i trim the side mount brackets shown right where the bolt holes are, the bracket will fit right in between the last 2 slots on the grill on either side. Ill use rubber pieces to isolate the screws a bit from fan vibrations and road vibrations:
Aluminum External Transmission Fluid Oil Cooler with 10" Electric Fan Towing New | eBay

Here is my mock up of where it will be using zip ties, bolts will be used for final installation:



I picked up a 3 core all aluminum radiator off ebay as well, it will fit right behind the trans cooler and as you can see in the photos... will JUST barely be far enough away from the trans cooler fan to not touch. Should get a good wind tunnel going forcing air through the trans cooler and directly through the radiator.

Here is the radiator for those that might be interested:
New Jeep Wrangler TJ YJ 3 Core Row Aluminum Radiator V8 Conversion 87 95 97 02 | eBay

Using my 16" electric fan that i upgraded to for my 4 banger, I will stick to it but this time im not going to run through the radiator fins. the fan and radiator are currently at my favorite metal shop getting a bracket mocked up. The bracket will seal off the fan to the radiator which will allow for max performance from the fan. The fan will only be able to pull air THROUGH the radiator fins and no portion of the radiator will be exposed to only free flow air alone. Pics of that to come in a few weeks.

Since the distance from kick down cable hole in the trans to where the kickdown cable needs to go is extremely far, i found Lokar makes a very lengthy stainless steel one:
Lokar Auto Trans Kick Down Stainless Hi Tech Kickdown Kit for GM 700 R4 60" | eBay

I also went with Lokar on the dipstick. You will have a very tight space to squeeze your exhaust through the firewall so a flexible dipstick sounded like a good idea to me.

The monster transmission cooler is bolted in!


The tabs got cut down so that the cooler mount tabs fit in between the grill slats. I cut down some breather tube to fit over the mounting bolts as spacers/isolators.




Also, the radiator is bolted in! So, i guess the front clip is done. kinda... The radiator looks like its seated too high which is confusing since it is supposed to be stock fitment.



Here you can see the spacing is PERFECT! the radiator sits about a quarter inch away from the efan for the transmission cooler.


Another angle... I had my favorite local machine shop make a custom aluminum shroud/efan mount for me that fits right over the radiator for maximum CFM from the 16" fan.


Here it is with the front clip back on. worried about hood clearance.


Distance between the motor and the efan is about 4 inches, not bad! It looks like there is a lot more room with the front clip off than there really is.




Also last note... the jeep is officially self supporting! no more jack stand holding up the trans/motor. They are still under the jeep but not touching the trans or motor.


You can see, this is a freakin' heavy motor man! These are stock leafs and the shackle is almost bottomed out. P.S. would you believe me if I told you those leaf packs hadnt even seen 1000 miles yet? thats basically how they looked when i picked my jeep up from the shop. Thoroughly unimpressed.






This past weekend was Orlando Jeep and Truck Fest at the Orlando Convention Center. I ordered up king coilovers with 14" travel and remote reservior along with 37" BFG KM2 mud terrain tires. woo!

Looking good. Won't be long now. I had the same thought with my Champion radiator. It looked like it stuck up a mile. The only issue I had was the cap was hitting the hood...BFH to the rescue.
