hey can anyone help me find the IAT sensor in my 02 GT?

 

That was directed at you...The joint bearings are made from a bunch of needle bearings that roll as the DS spins. The bearings are designed to roll and they roll because there is an angle difference between the DS and the yokes on either end. If you set you angles to zero the yoke would be aligned perfectly with the DS and the bearings can not roll because there is no angle difference to generate any pivot. This I was told is hard on the bearings and can lead to binding.

And just to make sure when I was giving a recommended number like +-2 that is a "parallel" number. That means you would adjust something to make the transmission tail hangs at -2 degrees and adjust the differential so it pointed up at +2 degrees. These numbers are parallel because a -2 degree line never intersects a +2 degree line they are equal and opposite so they run parallel. An ideal pinion angle should have a set of parallel numbers.

By design almost all transmissions hang at -3 degrees so you would want your differential to point up at +3 degrees to be parallel to the trans.

And by that note in some cases there is not enough room for say a t5 to clear the trans tunnel so they must hang down lower to do so. say -5 or 6 now the problem is that operating angle has become excessive and this can cause a vibration.

How are you you adjusting the transmission angle?

I have not tried adjusting the trans but it is almost perfectly level with the ground. I set the pinion 1 degree pointing down from being equal opposite of the trans. Ill go back and double check tomorrow at where the trans sits in referance to the ground.

 

Wrong section!!!

But, my guess says the intake air temperature sensor is going to be in the air cleaner or "the air ducting" that runs to the throttle body, in other words upstream of the throttle body. It will have a plug with two wires.

 

I think I would point the pinion one degree up if the tranny is one degree down.

The angles must be equal and opposite with a little imperfection built in so the needle bearings don't wear in just one spot.

It does not need to be rocket science (some folks think it is) but it does need to be close, and you have to follow the rules.

 

Oh yeah awesome chart..

And yes its not rocket science it just has to be okay. Your trans should hang in the -2 to -3 degree neighborhood.

I would avoid setting angles parallel to a trans that has a positive number. Make sure the trans has a downwards angle...

Your car looks like it sits pretty level so park it on level ground and I THINK YOU CAN use the transmission tunnel OR FRAME RAILS as a zero reference. IF the car were sitting dead level the transmission tunnel and rails would read zero...So for example if the trans tunnel or rails read +2 and the transmission reads +2 then the difference is zero and your real transmission angle is zero....Can someone else verify this as proper use for a reference number?

Your right and thats what Im trying to get accross is the my trans angle matches the level of the ground. Maybe I try to shim the trans mount so it points down a degree or two

 

Most American engines will point about 3º down, (even intake manifolds are made to compensate for this), if yours is dead flat at the yoke or front pulley I would be surprised, this being the case, I would be even more surprised if the right setting for your rear is 1º down.

I am not saying that it ain't so, just that I would be surprised.

You have a 4 link rear right? Leave the engine/tranny alone, and adjust your rear to match. Within the bounds of being reasonable, and in a Mustang, the angle of the engine does not matter, so long as the pinion angle is set to compensate.

It is all about how the tranny angle and the pinion angle relate to each other, for your car this is most likely the only factor that is going to matter.

 

i really wonder how you get the btransmission flat to the ground. maybe your rear is higher?
My T5 hangs down 5-6 degrees, and it should be at the 4 degree range. So I have a set of lowering engine mounts (half inch) to help with that. But they are not in car yet. So I really wonder how the heck you managed to get the rear of the T5 that high. can you measure what angle your car is standing on flat ground. Usually you can ignore this measurement.
As we all agree above. pinion angle = reverse transmission angle. No matter what angle the car as this is all measured with the same 'error'. I'm just curious how your T5 ends up being so high at the end. I can't possibly lift mine in the back as i would hit the trans tunnel ?!

 

again its an AOD...let me go throw my angle finder on my crank pulley real quick. that should be same angle right. Also my front is VERY low. Im sure that could be affecting it. Im running shelby drop, 1'' drop 620's that have a 1 coil cut to go even lower. handles like a vette with the 4 link rear.
