Hi all. I have recently purchased an old work truck for around the farm. It is an '89 Chevy Cheyenne 2500 4x4. Lately I have some problems from the tranny. What it's doing has got me puzzled. It has the OD transmission, but only will work in 1st and 2cd gear. If you drive it in "D" it will shift into 2cd, then when it's supposed to into 3rd(drive), it simply goes into nuetral. The max top speed I drive it in 2cd is around 30-35. There is no transmission shop here in my very small town to take it to, so this will be a DIY project for me. The only thing i have been told by chevy people around here is that it could be some kind of governer(?) on the side of the tranny, but they didn't know how to check and see if it was bad. Other than that I'm lost. I will list as many facts about the truck as I can think of. Any help would be appreciated. Thanks!

Hello,

You have the 700R4 trans. The governor is on the passenger side of the trans toward the back before you get to the transfer case, it's a round cap, the gov is behind it. It's not the governor though, if it was stuck or bad, you would take off in a higher gear or not shift at all, it would not cause you to neutral out. I am putting my money on the 3-4 clutches being burnt out, this is very comin in these transmissions. More than likely it's going to have to come out. Hope this helps.
