Damn whiny brats!! Give 'em a good spanking!

Seriously though, have never noticed mine do that, but with the carpet removed, you'll definitely hear a lot more, or more loudly anything that is there. Good bedliner can help with that though. I take it that everything shifts ok with it?

I'll have to have a listen to mine. I have altered my kickdown cable though. I no longer have that drop in power when it shifts to second from a stop. Always hated that.

I read bout doing that but am kinda hesadent on doing, I figured if it was maid to not shift hard mAking it shift hard might increase wear and tear, bout that rhino liner on the floor, it get pretty warm around the transmission tub, do you think the liner would bubble

Well, the white retainer the 4.0's have was missing when I got mine. Shifting was all over the place. Read up on how to properly adjust it. From there moved it one or two increments at a time, testing it each time I adjusted. I totally agree I don't want it to hard shift as it can't be good long term. Just kept until I found that sweat spot whereby it doesn't shift hard, yet doesn't have the drop. Huge difference it makes.

When I had my camry, could also adjust the maf. Holy crap could you nail the gas and it would just take off LOL.

See if I read that right, you can change how hard it shifts

It's not really changing how hard it shifts, but when it shifts, or more precisely 'kicks down'. Depending how you adjust it can cause harsh or hard shifts. My goal was finding where it's not allowing those harsh shifts, but gets rid of that dead zone as I refer to it, between first and second. I hate it. Get half decent pull from a stop, and when it does that first shift BAM! drop in power. I've got it so it just goes evenly and continually through gear to gear. Depending how I do the gas I can make it shift on the hard side, but that's not my driving style. I've also learned over the years how to feather the gas to get it to shift when I want as well. Helps to keep rpm's where I want and give better gas mileage.

Might have to look into going that route, cause I don't wont the hard shifts but would like a good transition of power through the gears

Just have to see what the procedure is for adjusting it, then just do it a wee bit (I did one to two notches) at a time. Took about 20min to get where I wanted it.

Hey guys! Been reading this forum since I bought my first tj a month ago. Wanted to let you know that the cable not only controls kickdown but also controls shift timing and apply pressures in the clutch packs. Too tight and you get hanging, hard shifts. Too loose you get stacked sloppy shifts, and can lead to slipping. I build, so I know those transmissions. Cumbersome at times but great trans.

What happened to mine is it just didn't have the retaining clip at all. So shifting was all over the place. Some days was fine, some days shifted on the hard side, others way to soft. Figured something was up and that's when I found the clip missing (4.0 has just a small white retainer clip, not sure how the 4.7 is). So started playing with it, as it was a known mode on the gen3 camry's. Couldn't get it right so read up on how chry-co said to adjust it. From there it was the normal 'dead zone' my ZJ had. So the light bulb went off, and wondered if I tweaked it what would happen? Ended up with a smooth shift all the way up from a top accelerating to highway speeds. Just seems to behave better. Don't notice sloppy shifts or any slipping, so hopefully all is well with it. I tend to feather the gas though to get it to kick down and drop rpm's when I want as well rather than let it sit at a higher rpm for no good reason. Been doing it since my first XJ. Always find certain speeds when you think it should drop down, it doesn't unless you accelerate and it then does it, or decrease speed. I perfer to stay a constant speed.

It's all about the sweet spot man. I tend to drive with a bit of a heavy foot, and most of the units I build are behind a diesel so we like them a little on the snug side. A side note: when you're ready to build that trans, it'll cost more but all of the internals of a Cummins unit (steel planets, more clutches) will directly replace the weaker gas stuff. Good for some serious off-road fun. Happy trails!

Always good to know! And yes, the sweet spot. Makes a huge difference driving it since I adjusted it. Hopefully this will give me a few years of good service before I have to worry about it. Was replaced with the engine when i got it, but engine went and had to be rebuilt. Still recovering from that one! Long Story. LOL

I have the interior of mine bed lined as well, and yes the tranny tunnel does get warm but it isn't hot enough to cause the bed liner to bubble over. You'd have some serious problems if it got hot enough to bubble it over.
