Transmission Problem (32RH Auto.. I think.)

I have an '01 Wrangler Sahara and it's still mostly stock, besides the guitar amp speaker I wired next to the stock sub in the console So I'm guessing it has a 32RH auto tranny? I couldn't find my problem anywhere else I looked, no matter what keyword I searched. I guess nobody else has this problem..
Anyways, when I start off from a dead stop, it either grinds like hell and shakes the whole Jeep violently or revs to somewhere between 2 and 4 grand and then catches and lurches forward. It also does the high rev thing when trying to shift from 1st to 2nd. Mind you it's only a 3spd auto, so I thought, "Why not try manual shifting for a while?" If I feather the throttle every so carefully, it slightly alleviates some shaking and grinding, but I still want to lose my lunch after it stops. Honestly I feel unsafe trying to merge into traffic because it revs, but doesn't engage for a few seconds. I've heard maybe the throttle linkage, but to tell you the truth, I don't know where it is or what it looks like. I'm 17 and a total noob to vehicles. I also thought maybe the synchros were out or it wasn't catching the passing gear, but it makes me sick to think about so I'm just gonna go with maybe too tight of a throttle linkage for now
Whew! Sorry for the novel. I just really would like to get this fixed so I don't, like, die trying to merge into traffic. lol

If you have a three speed automatic, you have a 32RH, also known by various names like A904, etc. Automatic transmissions do not have sychros, so that is not your problem.

It seems to me that you have two things wrong, one, your low/reverse planetary is shredded, and, two, your clutch packs are fried. Whether or not either or both are true, you definitely have a major problem and should not drive your Jeep until you get it fixed.

Drop the pan. If you see chunks of metal in it, your planetary is toast. If the fluid smells burnt, your clutches are toast. If neither is the case, you might want to check your drive lines and rear end just in case, but I fail to see how they could be giving you those symptoms.

If your transmission is toast, it is time for you to learn how to fix it yourself as you probably cannot afford to have a transmission shop do the work for you. That transmission is easy to work on with nothing complicated about it at all. It would be a great starter project for you to learn about how transmissions work.

Did a normal fluid/filter change(didnt disconnect the trans cooler hose and pump the torque converter clean) and the magnet looked pretty normal; nothing bigger than thousandth inch shavings and a little silver goop. The fluid was almost black though.. I put about 4 quarts in and ran it around the block a few times and it still only doesnt shake sometimes. It depends on how much Im pushing down on the accel too. I bent the throttle cable geometry bracket to a pretty good spot to where it shifts at the right time, but still; has trouble shifting sometimes. I bet its the clutch. I replaced the U joint closest to the rear diff a while back because I thought the same thing. Thanks for your help!
