Question about 1997 Chevrolet Blazer

1 Answer

97 transmission pump

While installing a used transmission, the torque converter did not go in place correctly therefore damaging the pump ( broke off the 2 small ears we believe goes to the pump). Once the transmission was in place the truck was started but won't shift. Once we took the transmission back out we noticed the ears were broke off the pump. We are looking to find out how to change the pump. We are hoping the pump off the 1st transmission that we took out will work on this one. We are not sure how to go about changing it. Looking for a manual or information on how to do this.

    We did the above. We removed the pump from the old transmission and replaced it with the one that was broke from the second transmission the we put in. Everything was installed and the truck is now running. The truck will not shift into overdrive and won't shift into first gear. Reverse, second and third gear shift fine. Just wondering if you could make any suggestions as to what is wrong with it now.

    Thanks

Just remove the front pump bolts, you will need new O ring seals, DON'T USE THE OLD ONES OVER, the pump will be hard to remove, but it will come out, have the trans pointed up or all the fluid will gush out on the floor, when you install the new O rings use good old Vasoline petroleum jelly ( heap generic works fine also) to lube the O rings, be very careful putting the pump back in or you will tear the new O ring seal and all you did will be for nothing, really lay the Vasoline on there, the more the merrier!

Whats wrong with my transmission


Two things come to mind. There are many though. First, did you put the bolts in for the torque converter? Even the best of us, forget some times. Second is a bad pump. It's not hard to break a pump either. If the converter is not set in place and you have to pull the transmission to the engine with the bolts. The pump just broke.
But again, there are many things inside the transmission that was already bad/broke and will not engage.

A 97 2.6LT 2 wheel drive auto Rodeo,took box out when i put it back in it haze no gears like its not getting oil,.why


the problem may be in the installation process of the box
the correct procedure is to put the torque converter onto the shaft of the transmission first and push it all the way back to engage the oil pump for the transmission
install the transmission then pull the torque converter forward to install the bolts through the flexi plate
putting the torque converter in first then putting the box up generally results in the drive for the oil pump not connecting properly in the torque converter

I cannot get my transmission back in.


Check the pilot end of the spline shaft to make sure it did not get damaged, check the depth on the half shaft that spline fits in, look for index guides on both housings, also hope that you did not preload the crank shaft bearings if the issue is with the spline or the half shaft.

When changing a pump rotor, tourque converter, gasket and filter on the transmisson, would you have to take apart the transmission to get to any of them?


There is nothing called a pump rotor in this transmission pump.It has a gear type pump with and inner and outer gear.You would need to remove the pump from the front of transmission to perform this repair(suspicious that it would need pump gears and not have major internal transmission damage, never seen that in 25 years of rebuilding)but would not have to completely disassemble transmission.The filter can replaced by removing pan on bottom of transmission and the torque converter fits into the pump at the front of transmission.You would need to remove transmission from the car to install torque converter.Are you trying to fix a problem or understand a repair that has already been preformed?Let me know if I can help.Good Luck!

Just my Service engine soon light is on for the second time and the code shows Torque Converter CKT Performance or stuck


The lockup function in the Torque converter is not functioning correctly. Your RPM's rise when you come out of Overdrive. Do you have the button in the shifter that turns ON/OFF the Overdrive? You don;t get it at startup since you can't go into O/D till the engine is warmed up-bet as soon as you go into closed loop mode (when the O/D can work)-the light starts. Hopefully it's electrical outside the trans-if it's the converter itself-the trans has to be opened. Check TSB on this problem. Ut has to do with a transmission oil pump defect and repair procedure.

  4. If the groove is not damaged, replace the fluid pump support seal with a redesigned Seal (F77Z-7L323-AA). Refer to Figure 1.
  5. Do not replace the torque converter unless it is damaged or fails the criteria listed in the appropriate Service Manual and/or refer to TSB 96-26-12.

This is something I recommend having a Ford Dealer do since they have the experience with the job.

When I start to drive my ford explorer the over drive light O/D come on and start to flashing. How I can fix the problem?


he overdrive off light flashing indicates that a problem with your
transmission has been detected. Take it to the dealer or a transmission
shop and get it checked out. If you continue to drive the Explorer with
the O/D OFF light flashing you can possibly damage the transmission.


Ford has issued a TSB on this problem. Has to do with a transmission oil pump defect and repair procedure.

Torque converter will not turn after transmission bell housing bolts are tighten...what is wrong?


When installing a torque converter there are two separate steps for two separate shafts with two different sets of splines.You must first turn the torque converter when on the input shafts until you feel Both steps engage one at a time.And with each step the torque converter will go deeper into the bell housing.To tell if you have caught each of the steps correctly you will be able to easily turn the torque converter,even when the trans and engine are pulled up tight.There will even be a gap between the flex plate and torque converter.What ever you do don't use the starter to get the torque converter all the way in.Take out the two bottom bolts of the trans and replace them with 1" longer ones.Then remove all the other bolts from the housing.Slide the trans as far back on those two bolts as you can until the torque converter will turn easily again,then turn while pushing in toward the trans until you feel the converter slip in that last step.Slide the trans back up to the engine and make sure the converter still spins freely,then finish your install.My first trans I literally broke the transmission housing by not fully seating the converter.Hope this helps?
