Surging

Definitely need more information...
My '95, 302, 4wd, Ext. Cab, Eddie Bauer, w/4R70W transmission surges between 62-68 mph, regardless if it's in OD or not. It's something to do with the tone ring...truck was abused and I have swapped PSOMs, and VSS sensors. And I'm just gonna live with it since it has 253,XXX miles.

Have you checked for codes?
Did you purchase it this way?
How many miles?
When was the last tune up?
Does the PSOM needle waiver?
Does the OD light flash on the shifter handle?
This is what we're asking for...Need more information...

And yes on the PSOM. When does it begin waviering?
The PCM relies on the VSS and the PSOM to communicate together. If either are erratic, then that can cause a surge. I feel and see It when I'm using Speed Control (Cruise) when the speedometer needle waivers between 63-68mph. I can only feel and see it. If I'm cruising above or below the indicated speed of 63-68, I never feel it.
