Chrysler Repair: DTC 37 on Chrysler Lebaron, chrysler lebaron, hydraulic control system


Question
Hi, Sometimes it has an eratic shift from 1-2 gears. The other day when I put it in drive, came back and tried to upshift it would not do so. I turned the key off a few times and it worked. I really don't think it needs a overhaul. Any suggestions on what i might try? Get the shift linkage adjusted?

Hi I have a 1992 Chrysler Lebaron 3.0 with 4 speed automatic transmission having 57,000 miles on it. I am getting a fault code 37 and no one seems to know what it is. Can you tell me what it is and about how much it will cost to repair? Thanks!

Hi Mike,
My opinion of the code 37 in your situation is that it is a false code that is not applicable to your transmission. It is applicable to the non-electronically controlled 3-speed automatic transmission that is used with the 4 cyl engine LeBaron but not with the 4-speed automatic. This is not unusual. There are other codes that can come up routinely when the particular device is not actually utilized in the vehicle.
It means that the electrical connection for the lock-up solenoid on the torque converter has a problem with its circuitry. And there is such a solenoid on the the 3-speed. On the contrary on the 4-speed while there is a lock-up solenoid it is not controlled by the engine computer but rather by the transmission computer and fourthermore it is an electro-hydraulic control system that would only produce a fault code if the trans controller were read out, which can't be done with the ignition switch. So unless your code was readout with a Chrysler Diagnostic Readout Box II I would not consider it valid or anything to be concerned about. At worst, if the lock-up didn't work the gas mileage of the vehicle would decrease a few percent, but I don't think you would notice it.
So my advice is to ignore and enjoy the ride!

Hi Mike,
The shift adjustment is really easy. Set the gear shift lever in park. Then loosen the shift cable bracket at the trans and move the shift lever shaft at the trans to its resting frontmost detent position (which is park position, of course) then tighten the cable bracket. I don't know whether this will help you out. But other than that there is not much else to do except a readout for the fault codes of the trans controller as I described earlier.
