Manual Transmissions in Astro / Safari Vans (History Question)
Does anyone know the history of the manual transmission in our vans ? For example:

I have an OEM Astro 5 speed van. I have learned a wee bit about them....

When were they available ?;

1985-1989. Note, in 1990 they changed the shape of the dashboard. But newer ones after 89 had no pre punched holes to hang a clutch peddle. 85-89 had the holes in place, just hang the peddle.

Did it cost extra to have one ?;

No Idea, I have never ever looked into buying a new car, not even an 87 astrovan.

Who made them ?;

Borg Warner T5 Transmissions were installed into a few V6, and a bunch of I4 vans.

Where was the shifter located ?;

On the floor right beside the drivers seat, it's actually fairly comfortable location.

How many were made that way ?;

Not sure, I read somehere that there were about 18 or 1900 sold in Canada.

Etc.

These links are great!! Check them out...

When were they available ?;

1985-1989.

I consider this user to be the resident expert on 5 speed Astro's.They are not a very strong tranny however.

[MrJames]

Thank you Mike and Gary. I just never knew that a manual was available and find it fascinating because I like to learn.

We had a member,I think it was Logan,that converted a later model like a Gen II.

[doyoulikeithere]

The hardest part about converting a Gen II (or even a 90-94) Is installing a clutch peddle.
Thats why I said before that the vans from 85 - 89 have the hole stamped into the van already made to hang a peddle.
Then you just need a peddle and some bushings.
After 1989, they changed the shape of the whole dashboard, and as well the underside where the peddle hole used to be, in the steering column brackets.
So, Basically you will need to drill a couple holes, to push a pivot bar into with a peddle hanging down. (pix) and then install a master cylinder beside the one for brakes.
You can still purchase new cylinders and clutch sets from almost any parts store worth its salt.
After 89, they made other changes too, and I am ALWAYS on the lookout for clean rust free 87-89 vans.
Surprising how nice some of them still are !! BTW, I have seen 5 5 speed 4.3 vans around here on CL in the last 5 years.
I bought 1 to drive, and all the parts from another, not quick enough to scoop the others.
1 was only 400 bux and looked pretty clean. The others were 500, and 1800. All were Gone when I called.
Anyways, I digress... so, Heres where this has been covered a bit, before...

@doyoulikeithere Thanks for confirming my research into a stickshift retrofit. For my 1997 GMC® M11006, the gearbox I'm really after is not a BORG X WARNER® World Class T-5™ - rather, a TREMEC® TR-3160B with Small-Block Chevy bellhousing. Already anticipated shortening the propshaft, as the '3160 has about a foot on the T-5. Will need drawing copies of both gearboxes as part of researching the shifter installation, as the '3160 has three possible shifter locations, compared to one for the T-5, and I know about the crossmember issue. Assuming that I can retrofit a stock 1982-90 clutch pedal itself to the cab (where the fulcrum rod for the brake pedal is situated), what angles are needed for the clutch-pedal pushrod in order to clear the Hydro-Boost™ unit? I figured on either going mechanical (viz., cross-shaft and length-settable pushrod on the clutch fork, àux pre-1982 GM vehicles) or using a divorced master cylinder with the supply reservoir alongside the Hydro-Boost (with the external slave cylinder pushing the clutch fork).

There is probably a cable operated option ( from pedal to clutch arm) , as long as you are designing a 'one-of-a-kind' setup.
Fitting a hydraulic cylinder to the fire wall, in tour A/S bodies, in an appropriate area, does not sound trivial.
Many older German and Japaneese cars and trucks used cable operated clutch linkages.

Looks as though MAGNA® GETRAG® has a possible upgrade-gearbox candidate applicable to AWD as well as RWD: The 7MTI550, planned to back a 4-2.3 EcoBoost™ in the Ford® Bronco® from 2021, packs an even shorter low than the TREMEC® TR-3160B and a pair of staged overdrives. Ratios -- Reverse: -5.625:1; Low: 6.588:1; 1st: 4.238:1; 2nd: 2.365:1; 3rd: 1.453:1; 4th: direct; 5th: 0.776:1; 6th: 0.646:1. The Ford-to-GM input shaft and bellhousing issues are expected. I's anticipating using either a STaK® or Advance Adapters® ATLAS™ all-gear transfer case, should I go quad-levers for 4x4 (one for the 7MTI550, two for the transfer case; the fourth is a relocated emergency-brake handle).
