How do you replace rear trans mount on a 1990 olds cutlass ceirra?

Engine mounts could be problematic, trans should line up just fine. Get a tape and measure from the end of the trans mount where it mount to the engine as in the side that faces engine.. Measure to engine mounts, then check and compare the distances and see if they match.. Auto trans or Manuel??

Disconnect the engine torque mount on the top front , then you can pull the engine forward enough to reach the rear plugs

you will have to un bolt the front engine mount raise the engine and then you may be able to get to the pan bolts but if you're not mecanically inclined you need to consult your nearest dealership

I just want to make sure we are talk about the same item.

I hope FREEZE PLUG (silver metal cap) is same a your soft plug.


Please read on if it's the same thing........disregard my post if it's not


To remove freeze plug we drill a small hole onto the plug and use a slide hammer / body work hammer to slip out the cap.

Clean out the inner surface area real good before you put a new on.

It means that your charging system is in trouble. Possiblity is alternator...or the battery. Go to Schuck's/Kragen/Chief's/NAPA....they will test BOTH for free.

This car uses r12 freon that is the old stuff but you can have your system converted over to the 134a.

1990 OLDSMOBILE 3.1 6 CYLINDER ENGINE I WOULD LIKE TO KNOW LOCATION ON ENGINE WHARE CRANKSHAFT POSITION SENSOR IS LOCATED

Oldsmobile Cutlass Calais were made from1978-1991, and yes there were manual trans as well as automatic trans.

Here's some History on the Cutlass Calais.


March 1982 to replace Starfire, Lansing's version of the front-drive 101.2-inch-wheelbase corporate J-body subcompact failed to attract more than about 45,000 customers in most years -- except for 1984, when it garnered a credit­able 82,500 -- even though Olds tried most everything it could think of to sell it.

1988 the Firenza had offered all the J body styles, sporty GT and SX variants, overhead-valve and overhead-cam fours, optional V-6, and a confusing procession of price-leader and luxury models. But nothing seemed to work, and Olds gave up after '88. Firenza was no great loss, though, because 1985 brought a more-sale-able small Olds in the N-body Calais, called Cutlass Calais after 1988. Sized between Firenza and Omega on a 103.4-inch wheelbase, it bowed as a rounded, short-deck coupe in two versions: base and -- just to confuse things -- Supreme. Four-door sedans were added for 1986.
There was a lot of J-car engineering under the "modern formal" styling, and initial engine choices were the Ciera's familiar Pontiac-built four and 3.0-liter Buick V-6. Even so, customers generally liked this new bottle of old wine, snapping up 100,000-plus in the first year and better than 150,000 of the '86s -- about midway between the similar Pontiac Grand Am and Buick Skylark/Somerset.
For 1988, Calais coupes and sedans grouped into base, luxury SL, and sporty International Series (the last replacing a GT package option), but the big news was the first twin cam, 16-valve four-cylinder engine in American production, the Quad-4. Designed and built by Olds and offered as an across-the-board Calais option, it delivered 150 rather rough and noisy horses, but was claimed capable of much more.
Olds proved it by adding a tuned 180-bhp version for 1989. A more-useful option that year was a new 3.3-liter derivative of the 173-cid Chevrolet-sourced V-6. Replacing the Buick-built 3.0, it also produced 160 bhp -- and more torque than even the "High Output" Quad-4. To fill in for the departed Firenza, prosaically named Value Leader Calais models appeared for '89 with less standard equipment and restricted options but lower prices.
Enthusiasts surely shuddered when the 442 returned (sans hyphens) as a performance option for the base 1990 Calais coupe. Olds said the name now designated "Quad-4, 4 valves per cylinder and 2 camshafts."
Included in the $1667 package were the 180-horse Quad-4, five-speed manual transaxle, a specific version of Oldsmobile's FE3 sport suspension, meaty 215/60R14 performance tires on alloy wheels, full instrumentation, a cute rear-deck spoiler, and bold "442" exterior I.D. "Buff books" gave this latest 442 a lot of ink, but customers mostly gave it the cold shoulder.
Even a hallowed name on an honestly speedy little car couldn't convince many that Olds still specialized in high performance the way it had in the '50s and '60s.

olds mobile club of america should have your answer.

On those engines in order to get to the rear plugs (firewall side), you have to remove a bolt from each of the 2 upper motor mounts (they're called dog bones) at the front of the engine and at the same time you take a pry bar and rock the engine forward and put a block of wood between the engine and the firewall. Some dog bones have an extra hole in them so you can slide a bolt in them to hold the engine forward. It sounds like alot of hassle but it isn't that bad. Good luck!
