ATX Trans no gears / no park

[mcibusman]

Hello,

I am new around here, and new to the SHO's. I recently bought a 1993 SHO with 3.2L and Automatic Tarns. A friend of mine was driving it and it "broke" . Claims she was just driving down the road when it stopped going? engine reved up, but no movment. The car has no gears, speedo doesn't move, and it does not have park (car just rolls when you push it). Is there anything that commonly breaks in these trans? (I checked with a scan tool and I do get a reading of 485 rpms on the trubine speed.) I found a replacment trans for $600 (Used). Are there any other things I should be looking for on this SHO? It has 157,000 miles on it and it is all stock. Just looking to have a little fun!!!

Thanks,

Rick

Sounds like your tranny shift cable came loose on the top of the tranny.

Check you axles. Sounds like you either snapped an axle or snapped something inside the transmission. And when it comes to used transmissions, you get what you pay for...

I agree, sounds like tranny time. But I would check the cable first. I would NOT buy a used tranny unless you are VERY sure that it is perfect. I would look around locally and talk to some of the forum members about a tranny rebuild. A quality rebuild will run you anywhere from $1500-$3000 depending on labor mostly. There is a write-up here on the forum that gives a pricelist for all the parts.

The shift cable is hooked up. When you have the vehicle running and put it in drive nothing happens, but if you go to put it in park it "buzzes"(grinds) like the parts in the tranny are moving, and the park pawl is jumping back and fourth to get the parts to stop. have you folks heard much of the chains busting in these trans??

Thanks for all the help...

Once again. Check your axles. You either broke an axle or destroyed you planets in the transmission.

I have heard about a chain in the trans that can break (tranny time). I have a car that sounds similar. Does it sound like it isn't in park all the way? May the cable streched... But remeber the axles like already suggested. Good luck.

Yep I would definately look at the axles first. Remember that both of them do not have to break for the car not to move since power goes the route of least resistance. Which would be the broken axle. Transmissions usually don't just loose all gears without warning.

As everyone suggest look at you axels, chock the rear wheels and out it in gear. You might even want to set the e-brake and look at the axels. Should be able to tell at this point if it's a broken axel.

My newly rebuilt tranny cost me $1200 since I paid cash with a 12 month warranty. You would be better off going this rout than buying a cheep used tranny. Atleast if you rebuild you have the option of putting a trango shift kit in so that the planataries get the fluid they need.
Also, it wouldn't hurt to get a D4U1 computer.

With a broken axle the speedo will move. Sorry about your tranny.

If the fluid is not burnt and you have no forwad gears the Sun Gear broke at the weld on the rear drum,or low/Intermediate band is broken inside the transaxle assy.IF this is the case the overhaul should be much cheeper than a replacement assy.

Same happened to me in the shop now. Happened on a 6000 mile reman tranny....sorry about your luck

I found the problem

I had the 1993 SHO with no gears. I pulled the trans and found a lot of problems. Number 1 there were no bad axles, and no problem with the shifter cable. What I found was a 28" crack in the trans case on the outside, and I pulled the trans pan, found the magnet full of large chuncks of metal, and a 18" crack ing the case on the bottom. I replaced the engine and trans with one with 80,000 miles on it. I'll be firing it up next week. I hope to have it back on the road soon. Thanks for all the help. I'll be having parts for sale form the the donor SHO wich was hit hard in the front high. Let me know if there is anything you are looking for off of a 1993 SHO...

Thanks,

I think I located the problem.

It sounds like the drive chain let go. This isn't very common but can happen. I would suspect input shaft but you would have park and turbine speed would be 0 rpm.

I can rev my GP up in drive and get that 0 rpm turbine speed! Time to go cry.

At any rate, look to the drive chain. This seems to be a somewhat common problem, especially on harder shifting cars.

We have a stronger chain and different gear ratios coming out for the AX transmissions.
