Transmission / Overdrive: Three speed, column shift, rear trans mount question

[Craig]

This rear trans seems to be missing a mount.
Is this the case.

[oilnsteel]

No. Sometimes transmission cases were made for several different makes. Is that a T85?

[64studeavanti]

Studebaker cars used the rear mount on the bell housing not the transmission.

[bensherb]

True. There is NO mount on the tailshaft housing to the frame . There is a rear engine mount on the bellhousing, and front engine mounts on the lower front corners of the engine, but NO mount on the trans tail. The trans is simply cantelievered out there. This was not uncommon back when.

[Warren Webb]

There was a rear trans mount used in 65 & 66 when Studebaker used GM engines & had a different cross member under the mount. Those engines did not use the bell housing mounts.

This is why if a transmission and bell housing are separated that it must be dial indicated when replacing the bell housing. This is because the drive line will be subject to flex plate cracking on automatic transmission and manual transmission popping out of gear if the bell housing is not dial indicated.

Would not the fact that the mount appears at this rear location, indicate that it is a junk yard replacement transmission?
Wouldn't you expect simply two tapped holes to show?



probably a bad compare, but all i have.

[jackb]

No. I've seen that flat on many Studes. What I do notice (that relates to your "replacement" question) is the location of that flat near the crossmember. Could be weak bell housing biscuits or drivetrain located in the wrong alignment holes. I thought all crossmembers were dual exhaust "ready" ?

[altair]

I have three T96 transmissions and two are bare castings and one is drilled and tapped, he same configurations apply to the T 86. These transmissions were not exclusive to Studebaker other models used them also, Jeep for example. The top assembly could be replaced with a floor shift unit.

[Topper2011]

My GT uses the flat for the clutch pivot anchor.

[Craig]

From this one picture with a red arrow can the model of the transmission be identified?
T86, T90, T96, T89?
It is installed in a 1958 Studebaker.

[StudeRich]

It LOOKS like a T-86, but all you have to do to I.D. The CASE is read the T-XX Raised Marking Cast in, on the Right Side of the Main Case.

You do not show enough of the Rear to be sure, but it appears to be a Long Tail Trans. with a slide-in Yoke for a ONE piece Driveshaft correct? That would be correct for a '58.

It appears to be a V8 Overdrive, SHOULD be a T-86 with a 6 Bolt Top Cover, a T-85 SHOULD Not be in a '58 Non-G/H. They have a Removable Side Cover & No Top Cover.

The top pic, with the red arrow, looks like a 1958 T85 'long tail', it came in 58GH and maybe some other 58 C/K cars and taxis and other special orders. I bought one of those NOS from Lester Schmidt, back in the mid 1980s, and ran it for 100,000 miles in the 62GT, before foolishly swapping it out for a T86. I later went back to a T85 in that GT, but had already sold the long tail, so I had to install a short tail, which is still in the car today. It required a custom driveshaft, with floating front yoke. IMHO, the 58 long tail T85 is the best OD transmission out there for anything, 58 and later.

The second pic appears to be a T86, which I have found to be useless for my kind of driving.

[dpson]

I have to say the dual exhaust set up in the second photo is one of the strangest I've seen.

As I understand it, only a few models came with a "dual" clearanced "wing" crossmember. The GT's came standard with dual exhaust (except some export versions) and they did not have one. This is my
GT. But if you install a GM AOD trans the clearanced crossmember doesn't help anyway as the trans pan is in the way.
