Topic: Transmission Question

I have a 67' with a C4 and I have a leak coming from the shift shaft area of the transmission. Does anyone know if the seal can be replaced from the outside of the case with the transmission still in the vehicle?

Thanks
Jeff

You don't have to drop the trans. You remove the pan, then the valve body. After the valve body you remove the large retaining nut on the inside of the transmission that retains the manual lever. Once the lever is out of the case you can replace the seal.

The important thing is to reinstall the valve body with the proper torque on the bolts and to be sure the manual lever is positioned into the manual valve properly on reassembly.

Hey,

Thanks a lot for the information, I will give it a try.

Getting ready to start this project. Can anyone tell me where the seal is located once I get into the case? Is it on the shaft or pressed into the case? Once located is it difficult to remove and replace? Also are there a combination of O rings that need to be replaced to complete the job. Where can the parts be purchased?

Thanks in advance

Thanks but this doesn't show what I am looking for.

There should be a shift seal and kick down O-Ring

Can you tell me where the seal is located in the case and where to buy both the seal and Oring?

Thanks

Hey,

Thanks for the pictures ! Sorry for the questions: is the shift shaft seal on the shaft it's self or in the case?

If i remember correctly it is in the case. I think these are available at bulkpart.com  or if you have a Dacco transmission parts house or just about any transmission shop should carry these.
