Post subject:  Transmission not shifting into gear again.
I was driving from Clovis NM to Victorville CA.
Got 850 miles to Barstow and after getting back on the 15, the same transmission codes(P0700, 734, 735,. I believe) popped up and the vehicle wasn't shifting into 3rd/4th properly.
It was still drivable so I got it to the AAMCO in Victorville on Monday and I Greyhounded it back to Clovis the same day.
AAMCO calls me Wednesday and says the transmission is just fine and that the problem appears to be electrical.
They weren't elaborating quite well on it and they wanted me to take it down to either the dealer or a small shop they recommended.
The small shop wants $95 dollars for diagnostic and right now I'm strapped for funds and too far away to do anything(Liberty's sitting at my stepdads in Victorville).

Before I shell out anymore money on labor, is there a possible issue with any sensors not on the transmission?
I kind of want to get this solved without having to rush out there on the limited time I always have.

P0700 is a Generic Transmission error that says something else is wrong.

P0735 is Gear Ratio Error in 5th

P0734 is Gear Ratio Error in 4th


Possible Causes (From the Service Manual downloadable from the NOOB GUIDE):

Low Fluid
Input speed sensor or wiring bad
Valve Body accumulator cover failed
Cut OD or 4C Accumulator Piston
Broken or missing OD Bleed Orifice in Main Valve Body
Cut 4C Tower Seal
Transmission solenoid/TRS assembly
Cut or Missing #5 or #6 check ball
Worn Solenoid Switch valve or plugs
Cut OD or 4C Piston Seal
Stuck main regulator valve
Burned OD or 4C Clutch
Broken or Missing 4c bleed orifice in 2c/4c retainer
Broken reaction shaft support ring
poor machining on pump valve body face
loose/missing dribbler orifice assembly in reaction shaft support
cracked / loose / missing od/reverse piston bleed orifice
Broken reverse carrier hub weld
broken revers sun gear weld to reaction carrier

Pappy always told me to go after the cheapest fix first. Check the fluid level and remember to use ATF +4 ONLY.

After that, I would start looking at the speed sensor, then the Solenoid Pack.

How many miles on it?

About 48000 now.
It's all the way in Victorville right now.
But I'll take this and submit it to some friends there.

I should've also mentioned that the AAMCO out in Victorville said that there were no transmission problems upon checking.
The transmission was repaired just this month in Lubbock.

As for the diagnostic place suggested by the Victorville AAMCO, I may just have it driven over there for a look.
It'll take 25 hrs to get back out there by Greyhound and 14 by rental car.
With only three days off, that's too short of a time to crunch.

Couple questions with this.

1. How many times have you checked your transmission fluid since these repairs?
2. Did Aamco "burp" the transmission for you and add fluid after repairs?

I wish I could help you.... my transmission has been experiencing the same thing.

25 hours is s along drive for testing

If your transmission shop said that it could be an external electrical problem, then I would procure a pressure switch from a used junk yard (pulled from a good running transmission) in your area, there may be one closer by you than the dealer is.

From what I read, a bad pressure switch does funny things.

If it isn't the pressure switch causing the problems then I would have the used parts shop pull the other switches and test them one by one, I believe that there are 2 more, not sure.

The switches are easy to swap if you know their locations.

That would be the most inexpensive way to check it and without taking the long hike. Or you could always spend the big bucks and have the mechanics do it.

My Transmission is under warranty and is being repaired by the dealer. It has been in the shop for the past 6 weeks, and Chrysler still can't figure it out. A transmission specialist from Detroit is on the case now. They are determined to find the cause of the problem and provided me with a free rental. This could produce a brand new transmission for me with a brand new Torque converter again.

You can read about it here: viewtopic.php?f=5&t=74713

Good luck.

By the way.... sometimes those used parts shops can help you with getting under there and swapping the switches for a couple of bucks more.

Note: That the junk yards do not like to remove switches from a good working tranny if they don't have to. They prefer to keep the transmission intact and sell the transmission as a whole, but you never know.

If a used switch does fix the problem, you will know which one it is and you will have enough time to drive 12 - 24 hours to the dealer, procure a new one and eventually replace it. Or buy one online and have it delivered. :)

I'll have my stepdad check the fluids over there.
You know what they say about assumptions.
I assumed all was just fine after the transmission was completed and now I'm paying for it.

As for the poster below you, I'll see about getting those particular switches checked out as well.
But since it isn't here with me, I'm having this all done without me around.
1000 miles sits between myself and the Liberty.
Greyhounded it back to Clovis just to get back to work.

Haven't owned vehicles myself in awhile and feel that my brain isn't what it once was when it comes to these things. :( :(

It is a 545RFE Transmission, you're going to need to know that.

With all this discussion about switches, could the be a problem with the TCM (transmission control module)??
Could swap out a tcm from a 5.7 Hemi with the same 5 speed trany & try that too.

Post subject:  Re: Transmission not shifting into gear again.
I'll reread the work order from AAMCO Lubbock and see what all was done to it again.
My mind's been too flustered and baked to have really touched down on this the way I should.

Also I kind of wished I had my own garage to utilize.
Apartment car-ports are kind of restrictive.

Is there a parts supply house that sells these, or an EBay store?

Also, the same year HEMI 5.7 as well?

You can pick up the TCM from a local wrecker or eBay

Read though this thread to get part #'s etc.

No dice on ebay and the google searches come up with only sites selling an --sload of ECMs, but no TCMs.
Next bet would probably be the junk yard, and then shipping that off to Victorville from here.

Long, drawn out process made possible by distance and time-constraints.

Try finding a transport company to bring it home.

Are you sure they used ATF+4? Positive? Did they tell you they did and used some generic crap? Non-ATF+4 in a Chrysler transmission is known to cause all kinds of headaches.

I'm not wealthy you know.
Fix it up over there, and then drive it back.
I was entertaining the idea of renting a pickup/trailer and getting it myself.
But, too many rental places say absolutely not.


The way I see it I see it, I'm getting by fine without it for now.
If it takes my stepdad and a few others a couple more weeks, it's better than taking an unnecessary pay-cut for extra days off.

As I said, will have to go through more of the recent work orders when I'm not feeling like a zombie.
That could be very well be a culprit too.

It may be less than you think. Mine was brought out from south Florida to SF CA for $1100 I'd think yours would be <$400

All fine and considerable.
But, my stepdads place actually has tools and space to work on it.
However, I still may get it shipped out here anyway, even after it does get fixed.

I'll keep the road trips for rental cars.

Btw, who did you use to transport it?
