I was looking at jiffylube website and under transmission they have a tranny drain and fill and they have a tranny fluid exchange. Can somene tell me the difference?

also I called pep boys and they charge $140 for a drain and fill and at this other shop they charge $90 for a fluid exchange.

 

Drain & fill is just dropping the pan, putting a new filter on and top the fluid off....the fluid in the torque converter doesn't get changed. A fluid exchange (more commonly known as a tranny flush) is where a machine is hooked up to one of your tranny cooler lines while the car is running and pumps the old fluid out while replacing it with new fluid. This gets all the fluid in the pan plus the fluid in the converter & pump.....only way to change 100% of the fluid.

 

one only does like 3-4 quarts in the pan...and doesnt do the wholeeee damn thing...like 10 quarts for the flush

 

so which is better to get done? Any pros and cons to each?

 

Read this thread for more info.

couldnt have said it any better i used to manage a jiffylube and thats 1 of the only good things they have,lol. 1 thing i will say is that if you got alot of miles on it and havent done any previous service at all its no good.but i will say a flush is way better than just changing the filter and draining

 

100-140 still sounds really expensive if you have somewhere to do it yourself. If you follow the previously referenced thread all the way to the end, a flush takes about 15 quarts of fluid, a filter with pan gasket, and an empty 5 gallon bucket. Total cost probably closer to 50 to do the flush, if you buy name brand non-synthetic fluid and the ATP filter recommended.
JMO.

 

i agree it is expensive a lil too much

 

I just had a flush done on my company car at a local Valvoline that has the machine and it was $89.99. Old out.....new in. Pretty slick. Only part that sucks is you dont get the filter changed. But I didnt give a **** on my company car anyway.

 

i think at ez lube if i remember correctly we used to charge $79 and if u got a synthetic oil change they could hook u up. . just buy a 100 bucks worth of stuff they hook u up fat. .well we did. .

 

I wouldnt let jiffy lube or pep boys put air in my tires let alone touch my trans. If you do go that route make sure you tell the moron at pep boys to not lift the car by the tabs under the fenders.

 

 

Get a BG service, its runs new oil through the unit so its completely new, one warning that has been said of any company that uses the technique is to do it when its newer rather then at 100k, the new fluid maybe too harsh on the bands. Other then that I have used BG service on all my auto transmissions.

 

lol ill admit that most of them are idiots but not all,i understand about them not being able to lift a fbody right but thats not the only cars they do all day.i used to work at a tire place and every customer expected me to know how to put there spare away lol,but i know what your saying

 

flushing the system is your best bet....you can get under the car and just change the fluid...but thats not the advisable thing to do...you dont want to be mixing old and new tranny fluid

 

so everyone pretty much recommends a flush and filter change huh?

 

I WOULD NOT FLUSH IT.COST ME A TRANNY. After i had mine flushed and a new filter in about 10.000 miles later the tranny puked.My lines were pluged to the rad from metal shaveing.And the rad was pluged full of the metal bits

 

I did a flush on mine at about 85k miles and its runing just fine (knocking on wood). but if it came down to one of the 2 i would do a flush. no point on a drain and fill if its sill gona have old fluid

 

You didn't give your car's history, so we can't say for certain what you may need to do.

Over time dirt/sludge/grime becomes one with the transmission. Remove it, and things don't work like they did, new wear patterns develop on old and worn parts, and failure occurs soon. Flushing changes everything all at once and CAN (the key word) cause failure. It doesn't always, but many people have seen it occur.

But my rule of thumb is to flush only if it's low miles (less than 50k) on the fluid, and be sure you get your filter changed.

Me, I seem to have nothing but high mileage cars in the lot now, so I just drain it, change the fluid and filter, and refill. I do this to Z28, the Avenger, the Lumina, and the truck. It's easy, it's quick, it's less perilous.

Each car is on a 30k or less change schedule now, and will remain that way. I don't know why people avoid it so much. It's not any more difficult than an oil change if you don't have a drain plug, and hardly moreso if you don't.

 

fluid exchange is a 100% fluid change-a drain and fill is exactly what it says it is-drain and fill with a filter change.
