Tranny slips a little

I have an 84 chevy pickup 4x4 350 and the governors cap on the tranny blew off on my way up interstate 5. I pulled over as quick as possible, maybe 1/4 mile or so. once we fixed it on the side of the road, it started to act up. The tranny wasnt getting all the power coming from the engine but the rpms were still the same. It wasnt catching the entire time we drove back and you could feel it slip. getting power for 30 seconds and then the truck angles down from the lack of torque for about a second. now i think i hear somthing bouncing around in the tranny but havnt determined it for sure. now i am going to rebuild it...any ideas?

The governor fell out? Did you install the same piece?

You may need to re-visit the hasty governor install. They are specific to trans and application.

There is a plastic gear that could have stripped, a valve in the center that could have rocks in it, springs that may have fallen out, weights that could now be binding, a machined surface that could now be scored up.- To name a few.

How does a governor cap just blow off? Those things are ON THERE.

TH700R4?

did you fill the trans back up after reinstalling the governor? if you didnt, well then, you know why its slipping.
as far as governor covers coming off, it does happen, thats why theres retainer clips for the 350 or 700r4. when we see 1 that comes into the shop without 1, it gets siliconed in to make sure its in good and tight and doesnt come out.

to answer one, yes i did refill the transmission before leaving the scene or disaster. I guess it could be something that got in it but i dont know yet cuz we havnt dropped the tranny yet. As for the gear being stripped, when i pulled over and everything wasnt the temp of the sun, i removed the governor so that it wouldnt be lost and the gear was still intact and in good shape. from what i have found out, the person who did the rebuild on it last time obviously didnt put enough silicone because there was nothing on the cap and miniscule amount on the inside of the fitting. they must have used superglue or thought the press fit was enough to hold it. All i know is that ive been screwed. would anyone happen to know which tools are necessary to do a rebuild? possibly just to replace the clutch pack? I found a diff tranny but it just needs the clutch pack replaced. I certainly dont have the money to buy all the tools to do the job

Um, silicone? You shouldn't need a DROP on these translators. The gov cap is a tight fit with a square cut o-ring for a seal. There are clips that can be used additionally as mentioned already.

Find a local, reputable, independent trans shop. They have all the tools.

Best of luck.

I use silicone on the governor covers. You need to be careful with the amount.

I have seen gov covers blown off

Well my cap doesnt have any place to have clips, that i can see would fit anywhere since my cap is round and doesnt have a lip to attach anything on. I dont know how they go on or anything but correct me if im wrong.

along the same topic...what else, other than the clutch pack, could burn up due to a throttle valve cable being adjusted wrong. The other tranny im looking to get supposedly has a burnt up clutch pack but I dont know if the guy is telling the truth. It could be messed up big time because he thought the clinking from under his truck was just a branch and continued to trash the tranny. (I have no idea what sound the tranny makes when the clutch is burnt up) I dont know if I should get the tranny because mine could actually be in better shape than this other guy's. although the other tranny does come with new clutch pack and the rest of a rebuild kit

Band can also burn from TV cable misadjustment.
Gov clip, look at part 65 & 66, clip ends attach to case>> http://th350.netfirms.com/pages/back.jpg clamps the cover on like a Brake Master Cyl. cover.

depending on the year of the t-700r4 / 4l60 transmittin case, the holes for the clip over the governor cover were deleted by GM.

GM used a adhesive to retain the round governor cover
