My son wrecked his 97 626 he ran into the back of a semi trailer causing damage to the front end above the frame rails. The radiator, condensor fans and all were ruined. Both air bags deployed and of course the hood, windshield and fenders were ruined. He also hit hard enough that the right (passenger) side motor mount broke off the casting to his motor.
I took the car to a friend of mine who has a body shop and he installed a new front clip. I have since torn down the engine and replaced the block with a used one. On completion of this project which has taken several months I found out the transmission will not make the car move in any direction.
My questions are these...1. If a automatic CD4E transmission in this type of car is involved in a collision is there a pump assembly inside the transmission that might have snapped off? Additionally, I have removed the air bag module under the dash awaiting the installation of new airbags . 2. Does anyone know if the removal of the airbag control module would somehow affect the transmission going into gear, like a safety interlock feature?
But number 2, I don't believe there is any connection between the air bag control module and the OBD-II ECU. There definitely isn't with the OBD-I ECU (93-95).
the pump is on the back side of the trans near the driver side wheel well. more than likely the trans might be bad. they didnt have a good track record of being a really good transmission

Thank you for responding. The transmission was working great until his accident. I have heard that the transmissions go out more times than not when involved in frontal type collisions. Since I dont have the expertise or the patience to work on an at transmission I will need to find another one or swap in a stick. More time labor and money. It keeps me out of trouble and my son and girlfriend know where to find me at least when I have a project to keep me occupied.

any fluid leaks?? if the fuild had to be replaced after the crash and the fluid had not been changed in awhile, it could have been the deteriment of the trans. just one cause. without seeing it or being there its hard to tell for sure but those trans were not very good.

No the fluid did not need to be changed. The transmission has less than 6k miles on it since the rebuild. Transmission fluid is new pink in color. I did add an new trans cooler in series with the transmission and radiator. After the radiator before return into the transmission. Going to check the shift linkage cable and then see if I disconnect the transmission output line to the radiator if the torque convertor is pumping anything. Its possible I didnt get it seated well but I dont think that is the cause of my troubles. Any other ideas would be helpful and appreciated.
I think I found the problem. The torque convertor isnt pumping fluid out either transmission cooler lines. I messed up when I put the converter in. I am use to manual transmissions and didnt know I needed to seat the convertor in the transaxle then slide the engine up to it. I bolted the convertor to the flywheel and stuck it in the transaxle. Need to check the condition of the pump shaft ( I think that is what it is called). The shaft that comes out of the transaxle and the convertor meshes into.

Hi
The smaller centre shaft that comes out of the tranaxle is the input shaft for the transmission, behind that is the larger stator support (with splines) for the one-way clutch in the Torque convertor which does not rotate, If you look on the Torque Convertors' neck you will see two flat areas opposite each other on the outside of the neck, these are the drive tangs for the transmission pump & must be engaged with the corresponding drive "flats" on the pump. That is why the Torque convertor must be installed on the transmission before bolting to the engine as you have to get the 2 splines & the tangs installed simultaneously . When bolted to the engine it (the convertor) then is moved slightly forward when the drive plate bolts are installed. If you look down past the stator support past the front oil seal where the convertors neck goes when installed you will see the corresponding internal flat areas on the centre gear of the oil pump. Check that it is not damaged
I got the engine and transaxle seperated tonight. Torque convertor out and the tangs are not damaged...Seated the convertor this evening and will start putting the transaxle in tomorrow. Thank you for your response. I asked one of the guys at work yesterday about the problem and he too told me to examine the convertor tangs. I guess I got lucking. WIll know how lucky once all is assembled again and the tranny does go into gear.
You seem knowledgeable on this type of car so let me ask you a question if I may? The bushing inside the torque converter needs to be replaced on my son's car. I have a local transmission shop ordering me one and will install it for us. I have removed the old one all ready. The question I have is this. I hooked a drill to the input shaft for the torque converter that goes back to the pump assembly and the pump turns wonderfully and shots transmission fluid out the hole in the side of the shaft hard and strong. Is this a good indication the pump was not damaged when I install the tranny and didnt have the converter seated on the shaft? I have to assume since I didnt have the converter on when testing this that there is no way to build pressure inside the transaxle to determine if the converter were installed if there would be any fluid being pumped out of the high pressure line.
Hi Well where do I start, first if the pump seems to operating correctly it is a
good chance everything is OK. As you have not said which model 626 it is? I have had a look in the 92-97 GE 626 manual & the ATX in that model has everything reversed as in the oil pump it actually at the back of the transmission & the smallest shaft in the centre is actually the pump shaft which runs throught the turbine (input) shaft to the pump at the back.As for the bushing I am assuming you are talking about the one just inside the neck of the convertor. Just remember the smallest amount of dirt is death to an Auto trans so make sure everything is spotlessly clean. When installed in the transmission the distance between the end of the convertor (flat face where the studs are) & the face of the convertor housing is 14MM (0.551") This is a GF4A-EL model, there is also a LA4A_EL which is a completly different model but still has the pump at the rear. You can test the line pressure with a test gauge, there is a plug on the pump housing. Specs - Forward gears 60-78PSI Rev 110-146PSI.
