LaSalle transmissions - can anyone point me to an exploded view?

So a 49 trans would/could be that bulletproof trans?

 

short shaft side shift with mystery shifter

and converted side shift with Ford splined tail shaft

 

Looks like an old Ansen shifter,,did these ever come with OD ?

Plus the whole set up there looks so simple and straight forward

 

that's the Hurst Mystery Shifter,

no Lasalle overdrives,
but I've seen overdrives built into the torque tubes and of course two speed rears,
either could be used with the conversion in the second picture there

 

lol, I though you ment mystery ,,wonder why they called it that
I'm surprised that they did put OD on those seeing as how those cars were so big ( thinking along the lines of the Lincoln )

 

it's a mystery to me too

 

There's a better article on the conversion to Ford rear retainer...the one posted is the cheesy one with the guy marking the new holes with a crayon...I think I sent Kevin a copy of one (It'll be with the Cobb supercharger stuff) with a decent pic and dimensions of the mods for rear retainer, and I'm about to send one to someone else--maybe it could be scanned.
Rear extension was for shorter driveshaft--too long a driveshaft causes vibration problems, so in a luxury car it has to be in the controllable length range or two-piece shaft.

 

Let Me Know If Your Interested In Selling Some Of Your Lasalle Spare Parts..i Run A Lasalle In My 29 And Everytime
I Shift In To 1st It Grinds, Maybe Sincro Going Bad, Don't
Know, Maybe You Guys Know If Thats Why,,,

So what is it about the looooooong tailshaft thats so bad ?? Does a shorter tailshaft prolong the life ??or does the long one tend to make the end throw out of round??

 

Shortening the driveshaft is a positive in a long wheelbase car like a Caddy, but when you put one of those in a Model A or something the result is a ridiculously short shaft that produces too much angularity and slip joint travel. All it needs is a torquetube flange and lots of problems get solved at once.

 

Ahhh so to stay in a Caddy or Olds it's fine right ? Was under the impression it was one of those bad factory decissions


Funny thing is the drive shaft looked kinda puney compared to teh trans ,,lol

 

This a real thread from the past. Also do not over look a 37 big Buick transmission. It bolts to late 50's-early 60's Buick and Pontiac bell housings. You can convert them to open drive by replacing the main shaft.

 

"But it WAS a bad factory decision. "

Yeah--whyinhell did they make whole damn huge Caddys and Zephyrs just to get some bits out to rodders?? They should have just put the good bits into crates, along with an Auburn dash, and saved a lot of good steel.

 

also an little longer driveshaft weights less then
an 3 feet long tailshaft vs short tailshaft...

 

OK, I sent out some copies of machining dimensions for LaSalle to Ford conversion...can anyone post the things??

 

I will when I get home if nobody else has

 

I had one in my ford convertible behind a 352 ford police interceptor. with 4 11 gears it was the right ratios. was fast shifting and lasted a coulpe of years of hard driving . the front bearing finally broke and dumped parts that locked up the trans and the drive line was rotating the gear box with that big ugly stick beating me on the leg. I installed a packard overdrive box next. sycnro on first gears, short and plenty strong..

 

the long tail shaft trans should be used with motor mounts in the center of the engine , not the front plate type. otherwise you get a lot of stress in the belhousing , most nhra approved housings are a lot stronger than stock ones

 

Were there any different gear set avail. ?? in the ambulance ,limo,etc..the super long trans in the middle has N in a circle stamped on it,,then 1 7..

 

Not sure about different gears but I'm willing to bet that the long tailshaft began in 48 or thereabouts when the hydramatic auto transmission came out. by making the manual tailshaft longer this would make both manual transmissions and autos the same lengths so they could use same mounts and same drivelines, less part to make, easy interchange. That's my theory, i'll measure both or compare the two next time I'm messin with that stuff.
