Thumbs up 1998 5.2 to 1995 5.9 Research

Hello Everyone,

I am looking for some information in regards to my current project, I have been searching for information for several weeks and think I am close to having all the information in order to start returning the truck I just bought back to life.

I purchased two trucks in that last couple weeks and hoping to put together the most recently purchased truck. The first truck I purchased was a 1995 Regular cab, long bed 4x4 with a 5.9 motor with an automatic transmission. This truck runs very smooth and seems fairly sound for its age, except the transmission has failed. The second truck I purchased is a 1998 Quad Cab short bed 4x4 with an automatic, missing its original 5.2 liter engine.

Through my research so far I have learned that I need to use the sensors from the 1998 motor on the 5.9 from the 1995 truck. I believe the following sensors are the only ones that are actually different among the motors: Throttle position sensor, MAP Sensor, Air Charge Temperature Sensor, and the Crankshaft Position Sensor. Does anyone know if there is more then this that I need to address? I am going to purchase these when I do the swap.

I have contacted Hemifever by email in regards to have him set me up with a tuner for this project. I will be giving him the information in the near future so I can get that end of things addressed on the PCM side.

I have been reading to use the intake from the 5.2 on the 5.9, but seeing that I do not have this piece can anyone tell me what the differences are between them that would require me to do this?

I have purchased headers that I am planning to use on this truck also. When looking over the original exhaust manifolds I noticed a tube coming from the passenger side manifold going back up to the back of the intake I believe. The headers do not have a place to hook that tube up. Is this simply a matter of plugging the hole off on the intake or is there something else that is required to make these headers work? (This item is something I honestly have not researched on the forum yet.)

Finally the last of the Items I am fairly confused on is the flex plate and torque convertor. I am reading I need to address a balance issue where components have changed from year to year. I have the Torque convertor and flex plate from bolt the 1995 and the 1998. But I am under the impression that neither of the components I have are going to work. The torque convertor from the 1998 is in good condition, but I am unsure if it will work with the flex plate from the 1995. I am unsure of how to identify whether the flex plate has the balancing material or the torque convertor does. The torque convertor from the 1995 has very burnt fluid in it, and I believe if it is the right torque convertor for my project I will need to replace it instead of risking damage to the transmission because of the clutch material from the failed transmission.


Thanks you for any help you may be able to offer in my project.

The 95 manifold would have provision for EGR, that is what the tube off the exhaust manifold is all about. As of the 96 model year, EGR was no longer used.

If I understand this right, you wanna put the 98 on the road? You can use the manifold off the 95, just eliminate the EGR vavle, and block off the holes. The older manifold also has a spot for a second coolant temp sensor, which on the 98, wasn't used. (the two wire sensor does the job for both.)

Get a flex plate for a 98 model year truck, with the 5.9, you will have to do a bit of checking to see if the part numbers for the torque converter are the same by engine size. Dealer should be able to look it up for you. At some point, they changed which part was balanced, I am not entirely sure what year......

Thank you for your reply!

You are correct sir about the 1998, I do want to put that back on the road. In regards to the EGR; When you say to block off the holes, Do I need to remove the Tube Only and block it off?.. That appears to be easily done with a brass plug possibly. Do I need to remove the top piece located over top of where the tube enters also?

My biggest hang up on my comfort level with this project is still around the flex plate, and torque convertor. I looked on auto zone's website as a reference. I entered both a 95 with a 5.2 and a 5.9, a 1998 with a 5.2, and a 5.9. I looked up a torque convertor for each of those combinations and they list four different torque convertors. Each of the applications used a different part. I don't know if the pictures they used are a reliable source, but sometimes the teeth that the starter engages are on the flex plate, and sometimes the torque convertor. If I purchase both a flex plate and torque convertor for a 1998 ram with a 5.9 liter engine, will I correctly solve any issues with balancing. I am hoping to get this correct in the first try, so I don't have to pull the engine or drop the tranny to correct the situation after it is in...

Thank You!

I think you can remove the EGR valve, and install a block off plate, and solve all of the problems. My 96 had the provision for the valve, but, had a plate covering it, so, it's possible that they are easily available. Check at the parts store, and see what they got. (prolly need a gasket as well) Make sure that seals all the holes.

I agree with replacing both the flexplate, and the t/c..... you would be sure to have the correct parts that way.... and the stock t/c sucks anyway. Get a good one though, don't just get one of the 80 dollar specials. Spend a couple hundred, and never have to worry about it again.

You gonna rebuild the trans before you toss it in? (I seem to remember something along those lines? Or, was that another thread??)
