so $217 dollars later (yes more than what we paid for the transmission in the first place) see lesson #1 above, ha ha we had ourselves what we believe is a proper or more better transmission mounted shifter linkage - this one I was told came out of a Chevelle

and this is what the shifter bits looked like when they arrived, can't wait to bolt them on and give them a go shiftin gears
hopefully they don't position the shifter too far back where we have bench seat clearance issues kinda cool that the eBayer threw in that white shifter ball, I happen to have a shifter stick that I hope will work so this should give me everything I need |

Saginaw Specifics
When looking at a Saginaw transmission, the front input shaft will likely have one or multiple grooves cut around its diameter. These grooves are there to indicate the ratios of the gears inside the transmission. 0 grooves: First 2.84, Second 2.01, Third 1.34, Fourth, 1.00 1 groove: First 2.54, Second 1.84, Third 1.44, Fourth, 1.00 1 groove: First 2.54, Second 1.84, Third 1.32, Fourth, 1.00 2 grooves: First 3.11, Second 2.20, Third 1.47, Fourth, 1.00 3 grooves: First 3.50, Second 2.46, Third 1.65, Fourth, 1.00 (I believe ours has three grooves so it's this one) |
Re: Restoring Rusty
This ought to be fun. I’m watching. I know you are ready to cruise a new four speed.

so decided to clean the Saginaw four speed transmission a bit, using Mineral Spirits from Home Depot, a wire brush, and some paper towels

and here it is with the Hurst four speed shifter linkage mounted and my old chrome HURST shifter installed, not sure if this stick will work/clear but we shall see, it does look pretty cool though
of course couldn't mount the white ball do to thread differences not only size but also pitch, coarse vs fine, it's not easy fellas, really wanted to see that ball atop the stick |

When looking for a brand new Hurst shifter components I further learned there were two Saginaw transmission types the 441 and the 456.
Hurst makes linkage for the 441 but not for the 456. So naturally I believe I have the 456, lol. Though with that Chevelle style bracket I think it makes it a moot point as to which one I have the 441 vs the 456 as it mounts the shifter using the bracket and ignored the holes in the tailshaft. hope you is following all this it can get unnecesarily complicated and I still don't get how this is supposed to be a torque tube transmission as it accepts a regular Turbo 350 yoke and has a rear seal for an open shaft, but the graphic saying it could be off of a 1981-82 Camaro or Firebird makes me feel a bit warm and fuzzy inside |
Re: Restoring Rusty
The F-body torque tube mounts to the three holes on the bottom of the tailhousing.

A bushing bolts to the tail housing of the transmission and then a link connects the rear axle to that bushing to control axle rotation. It's basically a type of 3 link suspension. Looks like the Vega had a torque arm suspension as well. I found this picture here. http://dave.h-body.org/H-body%20Conversion%20Tips.htm |

The 3.50 first gear was used behind small six cyl engines, like the 250. Your 2.84 is probably right on the ragged edge for a 350, but I know you're a conservative driver. :) |
Re: Restoring Rusty
Is that a current pic of Rusty? Man what happened to the hood? I still like seeing you taking Rusty camping.

Rusty treated me to some scary transmission noises on the way to work this morning to where I had to limp it home after work. So I decided to open up Midnight Auto and go Def Con 4 on the ol' OD trans!
I lifted the truck up to the highest click on the Harbor Freight 6 ton jacks and went to town at nearly 10 PM it was still almost 80* F |

How does a one man with a bad elbow git the trans out by himself without a proper transmission jack you ask?

mandatory stare and compare of the GM New Process NV833 and the Saginaw 4 Speed
hard to tell from the pics but they is nearly identical at roughly 21 5/16 inches long from bell housing to tailshaft end |
