93 voyager trans problem

93 voyager, 3.3 engine, 4 speed trans. (PRND3L) 180,000 miles. Transmission has hesitates going into drive.

1-I have done a filter and fluid change to ATF + 4 (I do not know what kind fluid was in the trans) trans. flush. Magnet in pan did have a few filings.
2-Cleaned moisture out of 8 pin connector and applied elctrical grease.
3-Disconnected both negative and positive battery cables for approximately 20 hours.

After double checking that fluid was correct after fluid change I took for a drive. Trans shifted beautifully, stopped turned around shifting to reverse and then to drive (very little hesitation when put in drive) From that point went into limp mode.Again stopping and backing up then shifting to drive there was a quite noticable hesitation from reverse to drive.

Should I try input and output sensors or am I throwing money away.

Any and all advice is greatly appreciated.

The magnet in the pan had like a grafite film on it. The fluid was red not a pink and was not burnt. Also can anyone tell me where the trans control module is located and what it looks like. I am considering adding a transmission conditioner. I have the battery disconnected since last night so I will connect and drive and check for any codes. Thanks for advice.

UPDATE:

Today I removed the input and output sensors, cleaned them and checked connections.(Both seemed ok)
I also added the LUCAS TRANSMISSION FIX CONDITIONER, warmed up transmission before driving to make sure fluid level was OK.(Middle of HOT zone) Need to get another quart tommorrow.

Trans worked the way it is supposed to until I again stopped and shifted into reverse then back to drive and drove, it went into LIMP MODE, but after stopping and shutting off engine and starting again it did shift correctly. This did happen several times ( when in limp mode at a stop shifting from drive to reverse and back to drive engagement was very hard. I only drove about 4 miles, when I parked it went into limp mode less frequently but the hesitation of shifting into drive has been eliminated.

I did check codes after driving and they are:
code 12, disconnected battery
code 32, Short or open in the EGR solenoid circuit. Check for loose, broken, or shorted wire in the EGR valve wiring and connectors. Possible air fuel ratio imbalance not detected during diagnosis.
code 55, end of codes

COULD THE EGR VALVE AFFECT THE TRANSMISSION????

Thanks for advice

Looking at my ATSG A604/41TE book (dated 2003), code 32 is 2-4 Hydraulic Pressure switch fault. It's tested in 1st & 3rd gears every time they are on, and faults to limp in after 2 failures.

Code 55 was listed as reserved for future use.

I saw something on the Allpar board of someone having troubles after adding the Lucas additive. I would use only ATF+4 on this trans.:nono:

A Mitchell Transmission Manual had some TSB in it. TSB 21-01-95 dealth with delay engagement. Delays are expected if the vehicle has sat for several days. They tell you to check fluid level, correct, then replace the valve body with P/N 4659085 if it still occurs. There were TSB galore for this trans, but they fewer ones starting around 1996.

:2cents:Since it has so many miles on it, you run a risk of more problems by replacing/working on the valve body without an overhaul. Yes, see about the 2-4 pressure switch, but that probably won't help the delayed enagagement.

EGR valve a factor? I doubt it, but it is possible, and it may signal other electrical concerns.

A trans shop can look at the cvi's [clutch volumn indexes] with a special scanner. A high cvi means the clutch is worn out. A low cvi means something's broken or misassembled(new overhauls). But the codes you listed don't suggest this is a problem.

Thanks Rawtorque for the feedback.
When you speak of 2-4 Hydraulic pressure switch fault are talking about the input or output sensors????
How do you check for faulty pressure switch or where is it. Any idea where I can look up all these TSB's you are refering too?? As for the Lucas treatment I'll probably take the chance.

Thanks again Rawtorque for advice.

The 2-4 pressure switch is a part of the solenoid unit.
