Looking at your vehicle info, your vin is either missing a digit, or you've read it wrong. The 2.3 and 2.5 were never offered in a 4x4 truck after 92?, so there is a good chance your 3.0 is the original motor in your truck. Being that your truck is a 4x4, i'd be willing to bet you have the 5R55E. One way to tell is to open your driver's door and look for the vehicle info sticker. It should be on the cab. It has your tire size, vin, etc. Look at the very bottom of the sticker, to the right side. You will see a line going across the bottom of the sticker. There will be letters like T, and A. Look for the bold T. The T stands for Transmission, and below the T should be another letter. On my truck, it's D, which means my truck has the 5R55E. If you can't find this info, take a picture of the info sticker, post it here, and i'll tell you what you have. If you can find the T, then post back here and tell me what digit was below the T.
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.
