Separating the transmission

Oh yes I wouldn't rec'd anyone not have one even if just for insurance.

 

Got that sucker out. Its on the ground. Next step is to pull the motor.
Let me ask ya'll about turning the transmission 90 degrees. Looking at the back, is that clockwise, or CC? I wound up with one of the electrical connections right at the bottom. I was concerned it would damage it. Don't know what it does. Its black with 3 screws holding it in. This will be needed info when I put things back together.

im sorry if i missed something on this thread. Why are you pulling the motor out? If that was the case wouldve been easier pulling motor and trans out together???

 

I wish. I am investigating putting it back that way. The transmission cross member is solid. Welded in place. Most of the Fords and Chevy's i've worked on I would tilt the engine back and angle the tranny to fit it. You cant do that with the 5 lug tacos. I have watched a bunch of you tube videos. The only one where they put motor and tranny in together had the cab removed. I don't want to go to all that trouble.
The reason for this exercise is to graft another coil spring housing onto my white truck. It is damaged. Engine needs to be out so the welder has access to the tower. Then I gotta put it all back. Long term project. See more about this project here https://www.tacomaworld.com/threads/04-coil-spring-bucket-graft.745614/#post-26553633

 

Someone posted the actual FSM page that shows how to remove it. Rotate the top of the bellhousing towards the driver's side. If the connector you're talking about is on the end of the tail housing then that's the speed sensor for the speedometer.

There's only two sensors\connectors on the w59 trans and that's speedo and reverse light switch.

 

That's some good information. My question is, does the pic in the manual show from the front or the back? I must have done something wrong because the only way i got enough separation to get the transmission to drop was to lift the engine and move it forward about 3". Not that big of a deal for me because I had everything ready to move the engine anyway. But what about somebody who just wants to replace his clutch? Honestly, I am worried about putting it back in after this repair.

 

It shows the front of the bellhousing looking back. I've pulled my trans a few times without pulling the engine. It just takes some wiggling. It can be frustrating, but it's def doable.

 

It's the mating that always gives me issues.

 

Even if there isn't much room I still use the trans jack to ge as much alignment as possible. It definitely helps.

 

It took me at least an hour solo with lots of swearing and alcohol medication.

 

Oh boy. I can't wait for the fun.
I got the engine out just today!

 

You find out that reassembly is easier than disassembly, trust me.

Take your time when you reassemble for sure. I would put the transmission into place and then bolt the engine onto the bell housing. The engine mount on the passenger side gave me a of bit difficulty as well as some of the bell housing bolts. The magic ingredient is taking your time and do the job right the first time. Consider going EGR delete if this is can be done in your area it saves on the carbon buildup in the throttle body, intake and intake valves in the long run.

 

I am going to have to go look at my transmission more carefully. I guess first I need to pull it out so i can see it well. One of the earlier posts said I could remove the bell housing, but the bolts were inside. If that's the case I could not get to those bolts until it was separated from the engine. Like I say, I need to look. If I could reduce the weight and the mass its got to help.
btw what is EGR delete?

 

Since you have the engine out there is a pipe that runs from the exhaust over to the throttle body and that pipe should be located behind the engine. Its common to remove it and block it off at both ends. When you remove the EGR electricals you can slip in a 10,000 ohm resistor on the female side and type it up. The 10K Ohms resistor fools the computer. Some will say that th continuous airflow into the intake will be too warm when you do an EGR delete. I personally feel not to much.

You should not have to remove the bell housing from the transmission. Just situate the transmission into place before you install the engine.

 

Gotcha!
So this is emission control. Should I get better gas mileage? The tiny 2.4 only gets about 25. Disappointing. I thought they had it choked down.
Let me ask you this, since you've done one of these 2.4s. Do you turn the engine the 90 degrees where the starter is at the top, and the shifter knob is at the 3 oclock position, or is the the other way. Shifter at 9 o'clock with starter hole at the bottom?

 

Its to reduce NOx by allowing some of the exhaust gasses to reenter the intake. Carbon buildup enters the intake as well. I haven't really noticed a performance increase.
When I dropped my engine in (2.7) I lowered the rear end and raised the from end of the engine to accommodate the front of the engine bay where the radiator goes. I never rotated the engine 90 degrees.

 

The 90 degree turn is right out of the FSM. May not be the same for the 2.7, I don't know.
For you to do as you describe you must have a removable cross member at the back of your transmission. All the old Fords and chevrolets had it. Sadly, my taco does not. Its a solid piece welded in place. That is why this job is so aggravating.

 

I have the 1998 Tacoma 2.7 engine 4X4 6 lug. So its different I suppose.

 

The 6 lug trucks are more robust, and repair friendly from what I have gathered, if I had it to do over from the start, I would get a 6 lug with the V6. Don't get me wrong, my 2.4 is a good truck, but the 6 lugs are grade above.

 

Mileage is better on 5 lug models since they sit lower and are lighter.

I have taken part in 2 clutches on 2.4's but can't recall which way they had to turn...opposite of the wrong way I reckon.

I do remember they had to be sideways.
