Is there anyway to look at one of these tranmissions while its still in the truck and identify it? Thing is , i'm not exactly sure what model my truck is.. vin says its a 2002 with the 4 cylinder.... but it has the 3.0 in it, and i had to get the older style oil pan gasket and plug wires at one time as the ones for and '02 would not fit it... so i know its older. I just really need to figure out which trans i have because i've got to buy another one for it .

IIRC, there is no way to tell by looking at the outside case. The only way to tell is by noticing the shift pattern while driving. The 4 at the beginning of 4R44E and the 5 at the beginning of 5R55E have to do with the "gear range". The 4R44E is considered a 4 speed auto, while the 5R55E is considered a 5 speed auto. However, you have to really know what you're feeling for to recognize what trans you have. The shift patterns on automatic overdrive transmissions are weird, as they aren't just a 1, 2, 3, 4, etc deal. The shift pattern for a 4R44E is something like 1-2-3-OD3, with the 4th gear being an overdriven 3rd gear. The 5R55E is something like 1-OD1-2-3-OD3, which means that the truck is overdriven in first gear, with the "fifth" gear being an overdriven 3rd, just like the 4R44E. However the 5th gear in the 5R55E is actually the overdriven 1st gear. It's just simple computer trickery, as the internals of the 4R44E and the 5R55E are nearly the same. The computer just adds an extra line of code to trick the transmission into overdrive after 1st gear. Simply, the 4R44E and the 5R55E are almost the same transmission with a few minor differences, the code from the computer is where they really differentiate.
Make sure you grab a 4R44E or a 5R55E from another 3.0 truck, as the 3.0 has it's own bellhousing pattern. A 2.3/2.5 or 4.0 trans will not bolt up to your 3.0 without a bellhousing change.

But to answer your question for others, that extra speed sensor shouldn't make a difference in my opinion, because the 4R44E equipped truck isn't equipped with the connector for that plug, and the computer shouldn't be programmed to recognize that sensor. Therefore it should just be a dead sensor. If you were to add the 5R55E to a 4R44E equipped truck, then the 5R55E will just become a 4R55E, since the 4R44E computer does not have that extra line of code to be sent to the TCU. But I think any vehicle equipped with a 4R44E would not have the same bolt pattern as the 5R55E anyway, so that swap would not work, unless the bellhousings are interchangeable. I think the problem with swapping transmissions is going from a 5R55E to a 4R44E. The 5R55E equipped truck has that extra line of code in the computer, and it is also programmed to recognize that extra speed sensor. So if you put the 4R44E transmission in, the 5R55E computer would not be getting a signal from that last sensor, which will either cause the O/D Off light to illuminate and put the trans in fail safe mode, and/or the transmission's normal operation will be affected due to no information from that sensor. Shifts may be off, or harsh because of it. But i'm not too sure on that aspect. There will definitely be an O/D Off light illuminated though.

Thinking out loud here......
But would the ECU even work with the extra solenoid/speed? |

The computer itself may work, but would probably have to be re-programmed to accept the signal from that extra speed sensor. In other words, that extra line of code would have to be written into the new program. I'm not too sure on the computer side of things.
