2.93, yet not a Brougham, & no yarmulke. I'm jealous, so, you likely did ok.
Seriously, congratulations.

Check for the rear floor vents.
We gotta figure out how to reproduce those things, if not improve on them.

I thought the broughams had 3.something rear ends.

Fleetwoods were either
2.563 (GM8) which is almost like having a 3 speed - should have swapped in 3.42 at my earliest opportunity.
2.93 (GW9) most 2.93 were Broughams, also most common gear for liveries (R1P) hearses (B9Q) & limos (V4U)
3.42 (GU6) which came with V4P, and should have been OE with every damnd LT1 car, damnit.

My 94 9C1 with the same engine and trans is still going strong over 201k miles.

I like to imagine 9C1 line pressure tables have something to do with that.
When your Fleetwood arrives, try 9C1 Main line pressure tables on for size.

Since you say floor vents I assume they would be under the seats and possibly not very visible for general photos?

Think they're pretty well hidden under the carpeting under the front seats.
Temporarily plug the front floor vents, the rears become more obvious, though still not easy to see.

I agree 3.42 would be nice.
My 9C1 has 3.08 and even that is a pretty tall gear but it's not a bad compromise for a daily driver.
I plan to do 3.73 with posi at some point.

Went from 2.563 to 3.42 in my wagon.
BEST MOD EVER, if only because CAFE MpG tests did not allow GM to make 3.42 OE for all LT1s.
The last 9C1-LT1 I owned had 3.73 from its previous owner.
On long highway trips, cruising over 65MpH 3.42 pays over 3.73 in MpG.
Your 9C1 may or may not need a driveshaft upgrade with 3.73.
Your Fleetwood will almost certainly need a driveshaft upgrade with 3.73.
Maybe give the Fleetwood the 3.08?

Hard to believe a 9C1 wasn't factory with posi but mine doesn't have G80 code and it's for sure open.
Interestingly it also has power mirrors but they are not heated, which from my research seems to be unusual.

Think G80 was optional for 2.93, 3.08, 3.231, & 3.42 B- & D-cars, including 9C1.
G80 was standard OE for WXs.
Don't know about heated mirrors (still looking for decent lil mirror bills for my side view mirrors).

I'm not sure what the main line pressure tables are or how to change them.

It's a pretty simple copy / paste operation.
Start a conversation with me if you want to know more.

I'll be sure to look for the vents though when it arrives.
Should also mention the dash is pretty cracked but I'll just cover it with a pad and probably eventually get it wrapped in suede.

Your bare feet may find the rear floor vents before your eyes.
As for the dash, it's a pity the aftermarket hasn't yet stepped up with decent replacements.

Touché, Fred.
Just 'cause GM wouldn't, though, doesn't stop anyone from installing a limited slip differential themselves.

 

[Marky Dissod]

Fred, may I paraphrase you?

Traction Control is redundant with a limited slip differential.
The LSD is preferable to traction control because it does not use the brakes.

 

[Marky Dissod]

They are redundant when installed on the same car.
If you like TC, put it first, if you like the LSD, put it first.

The LSD is preferable to traction control for me, because it does not use the brakes.

Traction Control will not work nearly as hard - if at all - if the limited slip diff does its job properly.
Prefer TorSen LSD to rebuildable Eaton, rebuildable Eaton to OE Auburn.

 

[Marky Dissod]

Good news:
disabling the 'foot fighter' traction control also disables the spark retard associated with it.
Bad news is you gotta open the glove box and press the button each time.

The grippier the tires, the less often the Traction Control will need to intervene.
Don't buy slippy tires!

A good limited slip diff will also make the Traction Control less likely to intervene.

Can it be disabled / disconnected under the hood permanently, without deleting it per se?
(As in, made vestigial, like an AIRpump?)
