Gears

Check your fluid level. Check the TV cable setting. If they're ok you either need re gear, fit one of those TV valves that needs more throttle position to kick down (not a good idea with the gearing cauing that problem) or drive in D! You'll not do your tranny any favours making shift up and down constantly like that.

Drive faster or slower. 
Half ton stuff is fine for 33's and 35's if you treat the throttle with respect. Check those adjustments before you do anything else. I would have thought you could get away with that gear/tire combo but you must just be borderline. Gears aren't cheap so be sure that that is the tire you want. If you're thinking of 35's, gear for them now. I run 35's with 4.10s and it is almost stock like. In hind sight I'd go with 4.56s.DUK5 said:
I have no trouble with shifting up and down.
I work for a auto group and we have several gm dealerships. I have had are axel tranny tech look at it, everythings fine he said I need to get bigger gears, are really replace the axels with 3/4 ton axels. I dont want to do that because I just bought wheels and tires. I can have new gears put in cheaper than peplacing the axels. Can I have my 10 bolts rebuilt and have a strong axel

I run 33s and 3.73s and really don't have much of a problem. Are you sure you're not stayng in OD but just going in and out of lockup? Thats really my only complaint about my setup and if I put a manual lockup switch or changed the setting somehow it would be much better. I actually think the lockup setting is much too touchy on the stock transmission since the engine is nowhere near bogging when it decides to go out of lockup. Running out of lockup builds more heat so I'd actually like to fix this.

Very likely his problem. I had this happening to me a while back and it was due to low fluid level. Not very low, but just enough. It looked like the correct level on the dipstick when cold but after a 100 mile run it was showing a bit low on the hot marks. I topped it up and that ended my problems.kp texan said:
But you're right, the lockup is VERY sensitive.

Well it's a little hard to tell without having a Tach to look at. When it goes in out and out of lockup, the RPMS change almost as if its changing gears but the change in RPMS is not as great. I'm not saying that's what your transmission is doing but it very well could be doing that rather than doing a full 4-3 or 3-4 shift.

had the same sh*t happen to me on my truck. it eventually lead to burning up my tranny. my advice would do like i did. rebuild it with the nonlockup converter. doesn't cost that much more and i couldn't really tell a difference in gas mileage. but it never did it again so it helpedkp texan said:
