And Po732-incorrect 2nd gear ratio I thought about trying to get another trans computer at the local salvage yard, seems like it is stuck in limp mode. There was no sign on the trans going out, just went out on my wife, in the middle of driving. Would another trans computer need to be flased?

Replying to: cridez (Jan 16, 2009 5:21 pm) Code 700 is a code the ECM put up to tell you there are codes present in the TCM witch can only be pulled out buy a proper scan tool. as for 732 yes second gear ratio there are some test you can do but to long to list here for that. Best to get codes pulled directly from TCM to help out in diagnoisis.but sounds like it proply one of the speed sensor but need codes to tell you or just replace them but could be a pump problem or valve body well there lots of pauseable causes. as for tcm from another vehicle you can but a reset or beak in presedure must be done or it could have suttering probs during lock up and same goes if replacing torque convertor and speedometer signal must be recalibrated aswell.

Replying to: leadfoot69 (Jan 16, 2009 6:15 pm) i went down and got both input and output sensors, still nothing. I guess I will try to get a trans computer in the morning and try that. How do I check that pin issue. I have noticed a lot of people have had a problem where a pin comes out not sure where thats located. Can this be checked by droping the trans pan. Thanks for the input.

Replying to: leadfoot69 (Jan 16, 2009 2:34 pm) The motor has 3.3 stamp on the top. The transmission is a four speed i believe as there is no overdrive selection on the dash display. The van has first and shifts into second. I can go as fast as i want - of course the RPM just climbs and I go faster in second gear. I have been afraid to red line because i do not want to make it worse - right now i can still drive to the Cottman Transmission store about a mile away. Right now there is no slipping. I just have reverse,first and second gear. The van was senior owned and garage kept so it looks new. At $3295.00 sold as is by Buhler Dodge Jeep this is disappointing. We do not have $1800.00 for a transmission (seems to be talk about repair price on the internet). Thanks for you help - will check later for your reply.

I put a code reader into the terminal port. The code is PO-720-01. The manual book states it is the "Output Speed Sensor Circuit Malfunction". My next question is that the "TCM" computer I have been reading about ? I see that they are around $199.00 refurbished with a warranty. Look forward to your help. sonofadocker Replies to this message: leadfoot69 (Jan 17, 2009 11:56 am)

Test ohms between tthe 2 terminals the ohms can not be 300-1200 if they are tcm is faulty.If they are anything else unplug speed sensor and do ohms test from terminal 54(14) and terminal 2 of sensor plug and 53(13) and 1 these must be under 5 ohms if more then fix wiring if less then replace sensor

Replying to: leadfoot69 (Jan 15, 2009 1:57 pm) O.K. bare with me as I am not real good with cars and have recently learned a lot over the last three or four weeks trying to figure out my issue.   I still do not know if it something that can resolved without having to rebuild my tranny or having to purchase a new one.   I had the codes read from the TCM at a transmission specialist shop "non franchise" and did not like his instant diagnosis thereafter stating hat I will need a new or rebuilt tranny.   He codes he pulled from the TCM I remember code:53 and there was another one between 51-55 so the second code was either a ,51,52,54 or 55 I do not remember sorry.   Can you please tell me if just based on those two codes there can would he really be able to say I need another transmission or rebuild this one at 1800.00$   Thank you and forgive me for my incomplete posts but I really literally only know what I have learned around here when it comes to cars.   Thanks in advance!

Replying to: roro121 (Jan 18, 2009 11:59 am) well codes 50,51,52,53,54 are clucth assemblies slipping and that means clutch assemblies need to be rebuilt. so saddly yes you are going to need major work on this tranny. codes 50,51 is same thing as other codes but adds a couple other things that might be wrong aswell witch are input/output sensors or tcm failure.but other 3 codes are clutch slipping. 50 is reverse 51 is 1st 52 is 2nd 53 is 3rd 54 is od Any of these codes put tranny in limp mode witch then you only have second gear So i would have to say tranny is in need if rebiulding or replacing. if you want to go a cheaper for now route you can get a used one from local wreckin yard and put it in they ussally come with some warrenty 3months or something like that. 55 is end of codes Sorry there isn't any better news for you.good luck.
#1720 of 1833 1996 Voyager Transmission Failure by sonofadocker Jan 26, 2009 (5:12 pm)
The Aamco by house my took the van in for a free exam. They found that the Dealership (Buhler Dodge Hazlet NJ) had taken the low speed sensor module out of the transmission and removed the metal shavings from the sensor and put it back in the van. I guess they should have pressured washed the entire transmission than just cleaning of the sensor an its harness. This cleaning off the sensor would make the van shift gears until the fluid had moved around all the shavings which would stick to the magnet again and keep the van in 1st and 2nd. The van did fine on the test drive and I bought it - The two mile ride after the purchase was enough time to make the sensor act as it should - collect the shavings and stop the shifting of gears.   $1926.00 for a rebuilt transmission. I was given a free torque convertor and two free sensors - savings of $227.00. The front seal on the transmission was also leaking.   Buhler Dodge has yet to contact me about the problem. Thank you for your advice. The only new issue with the van is the low fuel warning is going off no matter how much fuel is in the fuel tank.

My interior lights stay on unless in reverse or turned off by switch, ABS, Service Engine lights are on, I checked the codes and got P01698 it appears to be a transmission code as no message received from TCM tranny was replaced with in three years, also cluster has no signal coming in it has 12 volts and ground no 2.5 volt ref signal? were should I look for the culprit? The overhead console thermometer reads 115 F until I turn the lights on then reads correct.
