Here is a good website for some 4 speed info...Tim

One thing I have not found yet is the gaps for the selective snap rings, I read the factory service manual and it says to check the countershaft for .029" endplay but nothing for the speed gears. Any answers out there?

How did you bevel the edges? File or grinder? Tim

Quote:

did the detent mod that stanton posted last night to two different covers. Did one at a time to compare, and yes, there is a difference even just moving the detents by hand

In the process I was also able to find that pin between the two detent balls in my sidecover was missing this entire time I was running the transmission good thing I finally got this side cover apart

Ok, I found a NP833 from a chevy, its a low mileage one that was behind a 5.7 diesel. He wants 200.00, should I get it and rob it for syncro's and parts? Tim

I have had enough of these trannys apart to know what to use and what not to use.I have seen cluster pins and gears galled and flaked from ATF but gear oil filled transmissions always look better inside

Back in 1980, I worked for a Chrysler service Dept and at that time Chrysler was putting ATF in their OD manual trans. After haveing to rebuild and replace a lot of trans and parts, Chrysler sent out a service bulletin to replace all ATF fluid in manual trans with gear oil.
In my Hemi car, I ran 30 wt oil with a can of STP (when STP used to be the slippery stuff). Never broke anythign with it this way.

So I was able to inspect the transmission I just picked up and it needs new 307 bearings front and back as the old ones are shot. I have the SKF number for the bearings, but before I order them, was curious to know if anyone has ever used a roller bearing in the ball bearings place in order to increase the load capacity? Or am I best to leave it as a ball bearing?

I don't know the number for the more high load center bearing, otherwise I would look into that one as well.

Tim:

Those are getting to be on the scarce side. You might be able to buy it and turn around and sell it for profit. Especially if it's set up for a transfer case.

It sounds like a good idea to turn it, but I lose my a$$ on just about every deal I try to make a profit on....

I picked up that Chevy MY-06 833, it was a friend that had it who's wife drove the truck until it was totaled at 45,000 miles. It was sitting since 84, I pulled the side cover and the gears looked perfect. I have decided to pull the OD gears out of it to put in my charger once I get the correct shafts. The gears, syncros and shift forks are perfect condition.

I will find a nonoverdrive 3.09 gear set and swap the chevy tranny over with an A-body tailshaft and main shaft to put into a Vette with a big block.....it will still be stronger than a Muncie...

Gus,
That shaft spent exactly 12 minutes on the bench till I got all the papers burned. Then it was off to the lathe to check it. It has been in a unit out the door since the day after I got it!
Thanks though. It was a pleasure getting the shaft from you!

ok, is it possible to get shift levers that are shorter? That chebby 833 OD has shift levers that look about 1/4" shorter than my B-body ones. I need to measure to be sure, but would they make it shift faster or is there some interference issues with the shorter throw? Thanks Tim

I see this post goes back a few years??? Anyway, about 2 years ago I decided to try something different with my trans. Bare in mind that my car is mostly street driven, but sees about ten races or so at the track each year. I had run stock tranny's, Pro shifted 18 splines and slick shifted tranny's without the brass syncro rings. The tranny that has been in my car now for the past 2 years or so is a slick shifted 18 spline with the brass syncro rings. The main gears for 3, 4 and 2 are slick shifted.(every other clutching tooth removed). The 1/2 slider and the 3/4 slider are also slick shifted, BUT they are a stock slider for the newer syncro assemblies ('70 and up). I am also using the detent keys and springs installed so they are on the teeth of the sliders. This way, driving on the street is normal, yet when power shifting at the track, the wider "GATE" (with the missing teeth), makes for a very fast shift without messing up the gears. Absolutly no grinding when street driven.

Back in the early 70's Dick Landy used to have a traveling seminar where he would ago around the country to various Dodge dealers . I went to one where he had a couple of cars displayed . The only thing I remember is about the slick shifting of the 833 4 speed as thats what I was interested in. As noted in this post early on how it was done and thats what I did . It definitely improved the shifting of the transmission but also wear on the slider and syncro teeth. When I learned about Liberty Gears had come up with the PRO SHIFTED gear set up for the 833 I sent the gears into them to have them modified. That was like night and day. With my Hurst Super shifter the full throttle shifted were made with no missed shifts. Maintenance was minimal . As I up graded to a larger stroker engine , Liberty said I was going to have a problem. Why', I had ran this transmission for years without fail behind my mild built 440 . Well, they were correct, third run BOOM!!!!!!. So not to be defeated I ordered more gears and replaced the bearings again. Third pass BOOM!!!!!!! again this time twisting off the main shaft. Rebuilt it again and sold it shifter and all. Out in a Doug Nash liberty pro shifted transmission . To my surprise , a lot of parts are the same as the 833.

I yousta have a problem with the trans getting hung up trying to get into 2nd. This was at 7400 rpm with the gas held on the floor, and a quick stab of the clutch. Lost few races that could have won because of it. It didn't always happen, but it did too often. I tried a lot of stuff to cure it,including all the mods, different cover, different shifters, a Hurst reverse lockout gate. The best solution was to dump the Hurst ss3 and switch to a Long H pattern shifter. The improvement from a Hurst to a Long is like the difference from an Inland to a Hurst.

I never had a problem with the Hurst Super Shifter. It was the original one that came out in the early 70's . Just sold it off last spring with the Pro shifted transmission. The shifter didn't come with a reverse lock out until later. It definitely was a add on deal but it worked. It came with a piece if 1/4" threaded rod and a piece of silver plastic hose for a handle. Nice touch from Hurst in those days. LOL Never had the opportunity to shift a Long shifter. I have a Vertigate now which shifts well but I'm not really fond it.

I've been using the super shifter 3 forever, it seems. Did have a problem years back with hang ups going into second at full throttle. Did some "tweeking" with the shifter arm adjusters. I staggered the 3/4 arm slightly (1/8") toward third gear. Problem solved!!! Why? Don't know? But the problem going into second was cured. And, going into third was very sure and smooth.
