4604/41te Transmission

I have a 96 Caravan. The transmission stopped working. I need to know the location of the ground strap so I can check it. Also should I check the wire splice from the Solenoid and the TCM/EATX. Thanks

Ground strap should be located on a trans bolt in the starter area.

Can you give us a description of what tranny is doing or not doing. Is check engine light on? IF so check for codes by using the key dance method; on/off, on/off, on without starting engine.

Is battery in good shape? Battery terminals and cable ends shiney clean.

The wire splice question has popped up several times and no one seems to be willing to say. SOMEBODY PROVE ME WRONG.

If you don't get your answer try pulling the harness apart starting at the TCM and follow it to the splice.

Driving along, turning a corner then bang, trans stopped working. I have no gears. Starts fine, put in gear, rev it up and the trans makes a slight knock. The code says... shorted or open condition detected in one or more of the idle air controll motor circuts. I thought I would start with the splice and strap before thinking about a new transmission. If I find the splice I will make darn sure I post it here...Gloria

Do not get a reman from Chrysler and I heard about it lately.Chrysler puts on a chincy paint job on their remans with dirt on the case.Probally ful of dirt inside too.Their warranty is a 3 year,80,000 mile warranty.Jasper is cheaper than a Chrysler reman and has a better warranty,3 year 100,000 mile warranty and it is nationwide.It sounds like the beginings of the spider gear pin coming out and will ruin the case if not caught in time.This is a common problem too.Jasper fixed this by welding the ends of the spider gear pin to the final drive case

I would think the pump shaft sheared and it has granaded. i have 2 laying on the shop floor, same symptom. Did you ever hear a whine?

We can't seem to find the ground strap. Where can we find a good manual on how to rebuild this transmission. We can't afford to have it replaced and need to do it ourselves.

The battery is not in good shape. We are charging it now. What concerns us is the fact that it made a bang before it stopped working. We are going to start with the easy stuff first. I just ordered a book by Cliff McCormick called Chrysler 41te/A604, Rebuild Procedures. Hope it helps. Still can't find the ground strap.

You could make a new ground putting end of wire onto a transmission mount bolt by the starter area and attach other end to firewall.

Will try that in the morning.

Your idle air control motor/valve code has nothing to do with the tranny. It has everything to do with a stalling engine. Are you sure you're not having an engine stall issue instead of a tranny issue? When you take your foot off the accelerator to slow down at a corner, the IAC maintains the engine idle speed. You said it then started fine. That tells me the engine stalled. The code indicates the IAC may have failed causing the stall. Just want to make sure.

Take a look at this thread, it has a picture of ground wire for transmission:

Something I would try before removing trans if you have not already removed trans is disconnect the return transmission fluid line at the trans cooler, insert line into a bucket and have someone start engine and put in drive to see if the oil pump is working or shaft has broken like twistedtech suggested.

Also if and when you overhaul transmission be sure to install a rebuilt or new torque convertor, new lines to trans cooler and flush transmission cooler in radiator to rid system of all contaminetes. Installing a new trans cooler and bypassing old cooler would also work.

Hope this helps

The picture I posted in my thread shows the ground wire. Apparently it is a wire rather than a ground strap. I'm not sure, however, that a broken ground wire would make your transmission quit. My Caravan still runs and moves without that ground being connected. At worst it goes into "limp-home" mode, ie no higher than 2nd gear.

That ground wire is located near the front driver's side corner of the car. Its in front of the engine/transmission, underneith the starter, about in line with where the engine and transmission meet. Hope that helps you find it, and that a bad ground might solve your problems.

The previous poster gave you a link to the picture.

How much did you pay for a Jasper tranny? Thanks.

I found a ground strap attached to the firewall but the other end was attached to nothing. Can't find a ground attached to the Trans bolt. Could this be it?

Not really, because the transmission is bolted to the engine, which is grounded. Be sure to check all your fuses, the A604 transmission is electronic. If you're worried about the ground wire, do like that other guy said and ground it yourself.

You say you don't have enough money for a rebuilt trasmission? You can't afford to take your car to a transmission shop and have them rebuild yours? No doubt you could take the transmission out by yourself, Chryslers are easy. But a rebuild kit costs something like $150. But I beleive that only comes with clutches, seals, gaskets, and a filter. I can't remember the name of that part that broke in my A604 a while ago. But my dad is a transmission mechanic... even though I fixed it myself, we have a shop full of parts, you'll still have to go to a trans shop and ask them for some kind of part. They probably won't charge you much.

If you lived around Chicago, we would give you the best price on a transmission job.

After much searching at least found a chart. My 93 Eclipse has a strap to exhaust? 02 Caravan has chassis ground and battery ground driver side intake manifold. A loose strap at firewall probably goes to your hood.

Hello,several years back a thread on the location of a wire splice of the red ground wires for Chrysler 604 41te transmission. This splice and others are in the tcm to solenoid wiring harness that runs under the radiator from left side where tcm is to the solenoid on the transmission. I have 92 spirit with 70,000 miles on it. Transmission was bad.I just installed remanufactured transmission and I am getting code 41 and 42 intermittent. Never seen vehicle fight so much to get repaired.I removed the harness and checked each wire with ohm meter from prong to prong following wire colors.I found the wire splices
