TH 350 Dipstick Length - The 1947 - Present Chevrolet & GMC Truck Message Board Network

85/Silverado · 09-24-2015, 10:30 PM

Can anyone tell me the actual length of the stock dipstick that comes on a early 80's TH 350 transmission for my Silverado?
I'm tired of people trying to sell 10 different length's for a dipstick, that probably won't work correctly.

Thanks
Jack

If it wasn't midnight I'd go measure mine. If nobody answers by tomorrow I'll let you know.

I took my old one into Advance Auto and matched it up with one they had in stock. If you go by the fitment on the package, it will be wrong. I can't remember what the package said for the fitment, but it wasn't right. But I went by matching it with what I had, and it was exact. But from top to bottom, it is 21 3/4".

That looks like the Oil Dipstick, The transmission dipstick has a double twist at the end that you read to see if it's full. I know it's longer than that. But thanks
I would like to know the length (Or close) of the casing that holds the dipstick too.

This what you're looking for?

Overall length is about 35 inches from tip to the handle.

Then here is a picture of the reading level on it.

I tried to measure the casing but its such a tight place and it has bends. Sorry

Well it was like 2:30am, lol!! I guess I didn't see the word transmission. My bad, I just read dipstick and thought it was that. Yeah the transmission dipstick is a lot longer, sorry!!

Thanks Allot That should make the casing about 27 inches.
Cool

If you don't already have the dipstick tube, remember that its specific to 73-87 pickups. I tried several TH350 tubes from other GM vehicles and none would fit right until I was able to find one that came of a 78 C10.

When the guy installed my new engine he threw away the old dipstick because it had a hole in it about 2 inches above the tranny, so I don't know what it looks like.
