Thanks! I sure will do! One more time. Hehe.

Update! I unplugged the TCU as many of you recomended, it was one 7.5 amp fuse in the fusebox and a 10 amp in the wire to the TCU. The car has been standing for about 18 years so I'll do some electrical contact spray in the connectors and whatnot. And try to meassure the TCU to see if it has volts. Thanks you all! This forum is amazing for new Jeepers like myself.

When I start in D it remains in 1. Now it starts to try to shift gear in about 40kmh but really doens't mannages. : /

Tried this today, there's no difference with or without the fuse.

Update. I've changed back to the old oil filter today, no change. I manually changed the Kick down to somewhere in the middle. Now the car looses power near 40 kmh, it rews down in rpm and it feels like it tries to find a new gear but it doesn't. When driving downslope I can get past it and its the same symptome. It only changes gear until I'm near 60 Kmh.

Its the latter, 1-2 3 D N R P

Here it is! I manually pulled the inside of the harness to the right to adjust it today, as I've seen videos where the self adjustment does way more then it does when I do it. What happened was that the car lost power near 60kmh and didn't shift.. I re adjusted it as it is now and it shifted again only at 60+ kmh.

Unfortunately no change, I checked the oil again today and no difference when in neutral.

Thanks, the younger generation (90s) are pretty much forced to speak english in every day life if you're in the right trade. Yes, its just a metal wire in a plastic sleeve. I can fix a picture tomorrow! Thanks.

Yes, I thought that was the issue at first. I rechecked everything this evening. I drove the car, made the trans warm and parked it on a level surface, I filled from about just at the minimum mark on the stick to about right in the middle. No change at all. Perhaps there's a slight more noticable "clunk" when I put it into drive.

Hello! I have an 88 automatic Laredo that has been sitting for about 20 years... I've just got it going again with the aid of the forum and such. I started to change the oils to check the status of the viechle, engine, trans and gearbox. Thing is, the gearbox won't change gears when I'm driving. The gearbox doesn't change gears until I've reached about 60kmh, I let go of the throttle and it changes back into first gear at about 55kmh. I've tried to change gears manually by changing from 1-2 to 3 but nothing, doesn't matter at what speed I'm driving. I've checked the Kickdown wire. It doesn't look like its broken, its springy when I pull it and doesn't seem loose. Though, when I try to do the adjustment reset as many show in the videos on youtube, I move it all the way back and push the throttle. The kickdownharnessthing only changes a little bit with a click. The videos show a greater change then what happens to mine. What I recently did with the gearbox? Well, I took the pan down and changed the filter and the oil. There were not a single metal shaving on the magnets. I did a quick testrun when I first got the car going, and before I changed the oils.. I can recall that it changed between gears but brainghosts makes myself doubt myself a wee bit. I only drove about 20-30 kmh as I had my toddler with me in the car. As any amature I've consulted with AI and gotten the advice to either change the oil again, do some accelarations and hope it fixes itself, or its the govenor in the gearbox. Suggesting I remove it and clean it as dirt might have gotten into it. What do you pro comanche folks say? Anyone else had the same problem, or have a guess what might be behind the issue? Its a 3 gear gearbox on a 4.0 6 cylinder laredo.

Found it! The Cable for plus was gone. Might have found one that looked crisp… Now it runs! you truly are a Magician. Are there ”fuses” on the cable from the battery to this box? Or can i just replace it with a plain wire? Thanks again!
