I was in town coming back to work at lunch time going from red light to red light got to my turn light while sitting in turning lane pull up to light just fine but when light turn green it would not move tried everything put it in park tried every gear even reverse nothing heard nothing no fluid lose full of trans fluid road had been rough in town had it towed shop said they did not work on transmissions they said we think its the pump est was 1500-1800 to rebuild I am going to have it towed home and check it out myself can you tell me what could cause such sudden failure while not moving could filter have fallen off I was on very bumpy road or the transmission wire harness or pressure control solenoid cause this also the owner before me installed a remote starter on van could it have anything to do with this. I guess I was just shocked It pulled up to light fine what ever happen was while I was sitting waiting on a left turn light to turn green about 4-5 min. Thank you for any help I know cars but I am no mechanic.

First thing I would do is check the computer or codes?Have you done that yet? Also you will new to do a transmission pressure test. You will need to buy one to do that. Also it takes A expensive scan tool to properly do Full pressure test. Most likely if your not a good diyer its going to be difficult.

Can I not take a line loose and have someone crank up the engine if fluid comes flying out I have pressure if not I have lost pressure and other than a pump what else could cause sudden pressure loss can pump be replaced if its bad without taking transmission out if filter fell into pan would I lose pressure or would that not cause a pressure lose also does the pressure control solenoid cause anything like this to happen. I have to wonder if the rough road I was own caused anything to be shaken lose like the 19 pin transmission wire harness maybe the connection pins need cleaning out are their any fuses for the computer side of the transmission I need to check I want to make sure its internal transmission problem before spending 1500 to 1800 dollars I have a 20 dollar tool you plug in under dash I could see if I have any transmission codes are in the ECM. I going to have it towed home this Saturday. I work so much during week I don't have time to mess with it. I am just looking for any help with this 4T65E transmission I thought it was the strongest part of the van cause it works so well. Its sudden failure really took me by surprise. Then I found out today I use to make an extra 600 a month on my paycheck for being on call on weekends is going to be cut out due to budget cuts effective by the 15th of this month a 7 day notice. I want to thank anyone who tries to help me thank you saturntech9 for your help.

You cant just remove a transmission cooler line and watch for spraying fluid. Its just a matter of is there pressure or not. You have to make sure you have the correct pressure and the pressures are being controled correctly by the pressure control solenoid. I would start by checking for codes if you have any let me know the exact code numbers not code descriptions. Also the filters don't usually just pop loose. The connectors have locks on them so they usually don't come loose also. How long ago was your last transmission service?
