Trans fluid .

[Big_John]

I still use the screwdriver method in a pinch!! Works everytime.

Oh yea... That works and if you are comfortable doing it... By all means use a screwdriver!

I have learned on this and other forums to watch what I recommend. I never really know someone's ability so I try to err on the side of proper tools etc. I remember reading one thread about taking a harmonic balancer bolt off by bracing the breaker bar and hitting the starter. That's great for some guy that has turned a lot of wrenches, but in this case, it was someone that hadn't done much mechanical work. Then it becomes a dangerous thing to do.... And I refuse to advise someone to do anything dangerous.

I may pick up a remote starter to add to my sons inheritance!!

I think my oldest son has his garage marked off for where my lift is going to go. The running joke is he scratched his name on the bottom of my convertible so everyone knows he gets it.

Over the years, I've inherited tools from my Dad, my oldest brother and even my youngest son after they passed. I love using them as I think of them when I do

I was "scolded" on here once for saying how I used a quarter to short a starter relay. I still use a quarter.

Everybody I saw, back then, just used a robust screwdriver. They were always handy and available. Probably too much effort to reach inside one's pocket and feel around for change?

Probably didn't have any change!

That said, I don't carry pocket change too much anymore.

Sad to say when my younger died his wife got rid of his stuff, me in texas, them all in new york, I was left out and my father was not a tool man. All mine Ive bought over the years, would really like to invest in an outdoor lift someday! I dont do laying under the car very good these days. On a breezy day in my shop under the car is a good nap spot! As for breaking crank bolt loose that....have to pass! Thats why I bought my elec impact!! Only have one son so he gets all stuff including my 300, whenever I get frustrated with it and threaten to sell, he comes to her defense!

I was going to suggest a flywheel turning tool but don't remember if there is access to the teeth on the flywheel to use it.

Not that I've ever tried it, but I've read that disconnecting one of the trans cooler lines at the rad and dumping it into a pail while the engine is running in neutral is the clean way to drain the transmission. I presume this also drains the TC?

I have heard that mentioned earlier, that would be ideal! Unhook both lines, drain radiator tank at the same time. Wonder if that would work without damaging the pump.

I think you would only need to disconnect 1 line. And have an assistant cut the engine when you notice no more oil is being dumped.

In the early days of transmission flush machines, many were "manual", where the operator had to modulate the INPUT of fresh fluid to compensate for the OUTPUT of old fluid. LEST the transmission pump run dry! Which could compromise its lifespan. Some people were better at modulating the flow better than others. Later versions had automatic pumps in the flush machines.

ONE thing about the "flushes" was that they did not include a filter change, which some people figured was included when it was not. Different labor ops.

THEN it came to be that when a reman transmission was installed, the warranty on the replacement transmission would not be honored unless the cooler lines were also flushed at the time of replacement. Did not want contaminated fluid in the newly-redone transmission, for any reason.

Enjoy!

I have done this many times before. On vehicles that don’t have a converter drain plug or I can’t get the plug out clean. Unhook the return line and run in neutral. I usually hook up a rubber line run it out from under the car so I can see when it stops pumping and kill the engine.

 

[Mopar2ya]

Yea! That was a great way, but i was lucky and working at a dealer, had a buddy tech, he used the overhead hose/pump, put that in the dip stick tube, pulled the line and let 'er go!!! Great flush!! ( The boss happened to walk by at the time, didn't say anything)

I did this on my 96 camry - popped off the AT cooler inlet line coming from the tranny, aimed it into a bottle and quickly figured out that it pumped out about a litre of ATF in 15 secs. The engine/engine oil was already warm so I kept starting and stopping it as needed to ensure the gearbox didn't run dry. The shifts were noticeably improved, probably because the fluid hadn't been changed in 60,000 miles or so.
I don't know if you can do this with a 727 though.

Yes you can do this on 727 & 904 transmissions. The return line on the trans is the rear line and it is the easiest one to unhook. I have done in many times. Run the trans until it gets warm, unhook the return line from the trans, slide a 3/8 rubber line over the end and run it into a bucket that you can see. Block the wheels or set the parking brake, shift to neutral and start the engine. As soon as fluid stops coming out kill the engine. The only thing at risk running it dry is the pump and that will not happen unless you run the engine for several minutes dry. You will still have fluid in the converter so you can pull that plug if you have one and want to get most of the old fluid out. While that is draining, hook the return line back on the trans. Then drop the pan and change the filter, & clean the pan. You will always have some old fluid left in the trans because you will have a few quarts in the internal parts that you can't get out. One thing I always do is check that you have a magnet in the bottom of the pan to collect any small metal partials, most already have one but I add one if it is missing. Small old speaker magnets work great.

One more question, going to change filter and fluid in my 68 300. Original, stock 727 transmission. Whats recommended fluid to put back in? Only a few options now days. Thanks for the help.

Old cars do not need modern fluid. Dexron III of type F is fine.

Dexron 3 has horrible shear properties over time. Non-lockup torque converters will shear your oil. ATF+4 has much better shear properties and will last much longer in a 727.

Type F is bad for your 727, it will wear your clutch bands. It will give you harder shifts (if you like that sort of thing) but it will wear the bands faster than dexron or ATF+4.

I always thought Dexron was what chrysler ran and Type F was for the Ford transmission. I just want to replace mine with what is right and best. Stock pleasure use only.

I pump six quarts of this out the dip stick tube every 20k mile on my Dakota. That little truck has been properly abused towing 5 to 10k pounds all over the southeast since 1993. It has 250k miles on it.
Napa has it for $25 a gallon this month, no shipping charge. If it's ordered online for home delivery it must be purchased three gallons at a time. No more no less. Probably for packaging purposes.

Most GM car have no converter drain plug. I performed this procedure on my mothers 89 Cavalier w/ a pan removal w/ new filter. When I got mom her last car, (a low mileage Chevy Malibu), I performed the same maintenance procedure. Both transmissions length of service was extended to +130,000 miles.

Citgo Quatrosyn is the best transmission fluid you can get for anything but Type F and CVT
check it out
better low temp and high temp
NO viscosity modifiers to shear
Mr Shift Gil Younger of Transgo (RIP) said no type F ever
