I just installed a 700R4 in my street rod and I ordered the gauge from Bowtie overdrive to make sure that I adjusted the TYV cable correctly. After I got all of my pressure checks completed I call them with the pressure readings and they said they were good.
Today I road tested it and I have no 3rd gear. I call them back and the tech told me to shift it from overdrive to 3rd and call him back. So I did and I can manually put it in 3rd gear so he told me the 3rd gear valve was stuck.
I called the guy that rebuilt it (he is about 150 miles away) and he told me it was because the trans had been built for over 2 months, has anyone else ever heard this?
He is too far away for me to take it back so I would like to fix it myself. He told me to take it out and check it, yeah like I know where it is and what it looks like.
Does it sound right that the 3rd gear valve is stuck and if so does anyone have a picture of the valve body that I can see where it is located and how to remove it.
Any and all responses will be appreciated greatly.

Thanks and have a Blessed day,
Wade

 

Wel the trans should have been prepared and properly lubed to avoid that but if it was built dry then yes cast iron valve bodies will stick , If you want to try and fix it yourself give me a yell tomorrow and I will be happy to talk you through checking that , But your builder should be doing it
