I already did he's taking alittle while cuz they just moved.. He just got me a base tune to run the truck but it needs some adjusting cuz my 5.3 was faster haha but you can def tell the new engine and trans has a lot more potietial..

I had this problem..where at highway speeds the converter would constantly lock and unlock.

But Bumpers problem is that it shifts 1-2-3-4 within 20ft and then shudders/lugs because the converter is trying to lock but the engine cannot pull it at such low rpm/speed.

Is the speed sensor fine? Shifts are based on throttle position and speed... Pull it out and check for crimped wires or anything. Its on the back of the transfer case.

If the speed sensor was messed up would it not cause the speedo to read off or anything? I have talked with a couple more ppl that said it could very well be the maf but only time will tell on that. I don't want to kill another trans again just yet.

If it were a problem in the tune it would do it everytime because the parameters of the tune don't change ? Am I right?
