need some ideas from the ram experts
I have a 99 ram 1500 with a 5.2l. I just had the trans rebuilt from top to bottom (had the overdrive clutches go bad and wrecked the pump etc. Since then when I'm on the highway @ 100 km/h the truck "surges". I have read here somewhere someone suggested the TPS...any body have any other ideas? No, I haven't done the plenum, yes it needs to be done, and yes I saw all the parts they took out of my trans including the sensorsIt started doing it as the trans went. I was thinking maybe the pcms not functioning right, but no trouble codes. Any ideas would be appriciated.

Mine started doing the same thing on a long trip but my light came on and gave me a P0734 code.
Couldnt find the code in my book so I looked on here and found a topic that another member had the same code and claimed he put in a new output speed sensor and it fixed. I just changed mine yesterday but light is still on but no more issues. The sensor was only $16.99

I could be wrong...but i dont think the sensor would make the problem becausr its in the transfer case...also my sensor went bad once and i lost od speedo and tach but never had a surge problem...i would look into the tps

I gotta agree with ram360. I'm thinking the TPS might be giving you that symptom. I'd also definitely do the plenum ASAP!!! That very well could be giving you a slight hesitation/misfire from the oil it's leaking.

If it surges up 200rpms quickly and drops back and does at quite even intervals, then will bet it's the TPS. Probably won't get a code until it's real bad. 35 bucks easy fix. Mine was surging for a year, worse if I used cruise. Changed output speed sensor, didn't fix. Finally got a code, was the TPS. Like your truck!
