My aunt has a 96 Buick LeSabre thats starting to have transmission problems. She recently noticed that would clink when going up to highway speeds. She gave it to my uncle after getting a buick century and gave it to her hubby. However, the transmission doesn't act up when city driven. As the car is in good condition for having 150K, i suggested they buy a reman transmission. They do have a olds 88 that has a good tranny in it but has bad electrical problems. Combined both cars are worth $3200. I don't know if its compatible with the la sabres engine but being the same make and model they should be compaitible shouldn't they?. Heres their options:
Get a reman transmission
Swap out the one in the olds
Sell both the olds and LeSabre and get a newish car
I meant, does she know what is wrong with the transmission, and if so, roughly how much it would cost to fix it? If it is the tranny, then chances are it is an expensive repair as you would have to take it off the engine to basically do anything. I'm just wondering if you have exhausted all other routes before talking about replacing a transmission or buying a new car.
Well she nor my uncle want to spend the $ to get it repaired. However, their olds 88 could be broken up for parts as the engine and transmission have only 95K on it. Could someone whos a mechanic tell me how much they would get for both the car and engine/tranny combo if they were to sell it for parts.
The best place to call for that sort of thing is a full service salvage yard. They will already have an assemby out of the car and ready to go. A self service salvage yard, which is cheaper, will have you pull the parts you need.
Unless we are parting out a car or have extra parts.
Quoting MCOflyer (Thread starter): I don't know if its compatible with the la sabres engine but being the same make and model they should be compaitible shouldn't they?. Heres their options:
Both transmissions should be a 4T60E (which is an electronic version of a 440T4). You could swap them out, but then you will have to pay labor to remove two transmissions. If you buy a used or remanufactured tranny you will be only paying to R&R one.

You can take the trans out without removing the engine.
Quoting ScrubbsYWG (Reply 1): OR maybe you could find out what is wrong with it first and see how much it would cost to fix it
Good advice. Not every transmission problem requires a rebuild or replacement.

Not much. Around here (Detroit) you could get that for around $500. A 3.8 V-6 and a 4T60E is a very common powertrain. The car is virtually worthless without the engine. Unless it is in very clean condition. Average cars from the 90s with no engine and trans are worth their weight in scrap.
WTF does that mean? Is this a noise? Is there a performance problem associated with this "clink". Or do you mean a Colonel Klink?
Since it only occurs at highway speeds, I would guess it is related to the torque converter going in to or out of "lock up" mode. The torque converter lock up solenoid could have junk in it (they have filter screens) or be sticky from varnish build up. It's pretty common. If all you have is a noise or a single event, as you say, a "clink", so what?!
I'd service the trans, clean out the lock up solenoid screen and drive it until she blows. Then you can "Make a Wish" it into the corn field.
It might even be a bad motor/trans mount allowing the powertrain to shift in the sub frame.

Sounds like it could be a torque converter clutch issue. If memory serves me it engages in both 3rd and 4th gears.Possibly the computer is engaging/disengaging the "TCC" when it should not do so. (I believe this is similar to what KevinL1011 is saying)

TCC malfunctions will create symptoms that appear to be caused by other systems. For instance, if the Torque Converter Clutch (TCC) doesn't receive sufficient fluid pressure or doesn't engage smoothly, it creates a "chatter" during application. This often feels like an ignition misfire. A heck of a lot of people have been sold spark plugs, wires, ignition coils and injectors to cure a TCC chatter. Conversely, I've seen a lot of transmissions replaced to fix a misfire. And even if the condition is due to TCC engagement, the problem may not have anything to do with the TCC at all! A faulty Throttle Position Sensor (TPS) , Manifold Absolute Pressure sensor (MAP) or an intermittent output speed sensor could be the cause. It's always good to get a second opinion before condemning the transmission.
