It feels like my truck is shifting funny.. seems a little inconsistent through all the gears at times. And.. while cruising at 55-60 if I let off the throttle for a second and reapply the throttle it downshifts to 3rd.

here's a short clip

 

looks like you are getting 4th without lockup then lockup is happening.

 

I wouldn't say it is downshifting.

I don't recall it doing this before... Are you saying this is normal?

I don't see any issue, 

The tc will unlock when you take your foot off the pedal.  When you apply power your engine will rev because the tc isn't locked, and then it will lock.

Okay.. but I just dont remember it dropping out of lock up like this before.. usually I would let off for a sec and it would pick up where it left off. So maybe there was something wrong before.. ill get a longer video shifting through all gears. Thanks

Overall I think you should stop worrying about issues and just enjoy the truck   If you try to fix or figure out every little issue with our 15 year old trucks you will go mad. 

 

 

case in point I have a clunk in the front end, I can't find it, doesn't wear tires, and nothing has fallen off in the 40k I have driven the truck, so I don't worry about the clunk, if I accidentally fix it someday, great, if not oh well.

 

 

It is things like this that make me happy I have a stick. I have been looking for another truck and the autos around here are the only ones that are reasonable. So maybe I am speaking out to soon.

Well most know I'm on the way of having the 46RE fixed because I lost my direct clutch pack according to Dynamic. Got 160k miles and the transmission crapped the bed on me. Now my NV4500 manual everyone always scared of the 5 speed with the 5th gear nut issue. Nearing 260k miles and still working flawlessly. No issues at all I most likely clear 300k without a problem. Which is twice as far as my 46RE made.

I understand where you are coming from to a point.. but.. when you have fair amount of $$$ invested and depend on it to make a living.. you kind of want it to work the way you think it should. It just didn't feel like it was behaving the way it did.. or should. I do enjoy it and I also enjoy trying to get the kinks out and make at good as it possibly can be.  :-)

BTW.. I too had a clunk in my front end and it drove me insane. Turned out to be a control moving back and forth.

already replaced the control arms....3 times.....

 

I don't see anything weird going on personally.  

Okay... good to know. The reason I thought it maybe it was the TV cable is because a couple days ago when I was checking out the exhaust I noticed a black tubular plastic piece sitting on the cable kind of loose. So I pushed it backwards and it seemed like it snapped into place.. but wasn't sure if it was really supposed to. Today was my first real trip out of town since (with speeds above 50) and is why I noticed a difference. 

So... are you saying I should ignore any future problems or worry about them? There wouldn't be as much to talk about 

That plastic tube is a dust shield.

 

Yep just dont wait until the wheels fall off hahaha....however that owuld make for something good to talk about.

I once had a front wheel fall off my toyota celica. Not fun watching your wheel pass you by and sparks flying  Needless to say... I check lugs nuts 3, 4 maybe 5 times. 

I gotta say, everything in that video looks completely normal to me. My 99 would do the exact same thing. Typical sequence would be 1-4, then lock in 4th (right around that same speed) as soon as I left off the gas in 4th while locked, it would rev up a bit until the trans realized the speed was good and locked the TC again. 

Dont hurt to ask! But I would loose sleep over this! I've had some trouble adjusting to the 02 and it locking up 3rd & 4th. Still throws me off.

If the TV cable is out of adjustment you would notice it at lower speeds not where you are. If it is misadjusted it will shift 1-3 very early "Too soon at very low rpms" or very late "at high rpms", causing hard shifts.

What I saw in the video is how it is supposed to operate as stated towards the beginning of the topic.

I do think something is a little off... but not sure what. It has very hard shifts but doesn't seem to be late. They have always been hard and I attributed them to the "built" tranny. Since I did injectors the shifts feel a little harder... almost annoyingly hard.. jolting.  

You are using less to input than you used to due to the injectors.  Now 20% throttle is 100hp where as before 20% was say 75 hp.

 

So when doing you used to leave a stop light at 20% to now you might only use 15%.

 

That has a direct effect on how your Trans shifts.

Makes sense... still... somewhat annoying being snapped each shift :-)

I always adjusted my TV cable so it shifted about 100-200 rpm higher than stock due to heavy towing a lot, never wanted it to upshift too soon and lug or have to shift down again. I like the feel of a firmer up shift anyhow.

So.. what rpms is the shifting supposed to take place?

 

depends on Throttle Input. earlier for less TPS and later for more TPS.
