Replacing the burnt transmission in this truck. Tag says 4L5P and the replacement transmission says 5L5P. Everything looks identical, the electronics, wiring, tail housing, even trans filters. But the bell housings look different. Input shafts are identical. Torque converters were not identical. Can the bell housings be swapped? Replacement transmission came out of a 2005 Ford Explorer sport trac.

Hello, I'm Danny.

Even if they do physically bolt up to answer your question; no, they are not compatible. They are both computer controlled and are both different. My best suggestion is to find another 4L5P. Hope this helps and thanks for using 2CarPros.

Hello again.

Give me the vin- vehicle identification number and I can see if these transmissions are compatible. Get back to me and we'll go from there. Thanks again for using 2CarPros.

Just jumping in. While they might look the same they are not internally. Ford used a few variants of that transmission over the years. These two have different gearing and shift programming that makes them not compatible.

Well, is it certain that the stock transmission is a 5r55e?

Ford used two transmissions in the Rangers, One a Ford 4R44E and the other a Ford 5R55E
First is a 4 speed second is a 5 speed. An 04 should have the 5R55E. Base part number of
4L5Z-7000-AA.

Well, I went to the junkyard today and got a transmission out of an 2005' Ranger, same bell housing and everything so I should be able to hook them up, right? They look identical all the way around and I should only need to put a new filter in it. The old tag from the old trans is 4L5P-7000-AA and the tag from the junkyard trans is 5L5P-7000-AB.

Going by the interchange book the 2005 should work. However the parts catalog says they are different.

Hello again.

To make sure those transmissions are compatible you need to provide the vin- vehicle identification number for the 2005 Ford Explorer sport trac . Although each vehicle are offered the 5R55E transmission there are 3 different variations. There are the 5R55E, 5R55S, and 5R55W. Your ranger came with the 5R55E transmission. We need to know to see if they are compatible from the Explorer. Hope this helps and thanks again for using 2CarPros.

I don't have any info on the Sport Trac, however I do have the VIN for the other transmission I bought that came out of an 05' Ranger. It's 1FTYR14U35PB03147.

Hello again.

Yes, that transmission from the '05 Ranger is interchangeable with your '04 Ranger. They are both the 5R55E. Hope this helps and thanks again for using 2CarPros.

Thanks,

I got the transmission from the 2005 Ranger installed, with its matching converter, and new converter nuts. Poured in 5 quarts before I started it (as fluid just sat in the funnel), and got to 8 quarts before the stick began showing full. However, the transmission will not engage. When I select a gear I can see the rpm changes and hear the buzzing/whirring noise of engagement while under the truck, but there is no physical engagement. I feel like I'm missing something simple here. I am getting the following codes:

P1705
P0717
P0715

Hello again.

I've attached picture diagnostic steps below for the transmission codes you provided. Some includes wiring testing so here is a tutorial showing how to test wiring:

After testing get back to us with the results and we'll go from there. Hope this helps and thanks again for using 2CarPros.

So at the TSS and ISS I am getting a resistance of 1. However, on a different terminal on the TSS I can get a resistance of about 460 ohms, not that it matters I guess. I'm really confused, I have backup lights and everything but this stuff was working prior.

Wait, I think I messed up. The instructions want me to measure the resistance of the sensors connected to the transmission, or the wires going TO the transmission? The TSS on the trans right now is reading 78 ohms. Which should mean the sensor inside the transmission is good.
