Anybody used this kit?? If so, how did it work for you? Is it still good and reliable enough to tow with? Has the kit given you any problems? It seems like a great alternative to installing a AOD tranny.

"#727518. With these four parts you can convert your 727 transmission to a 518 overdrive transmission with locking torque converter. Lets say you drive an average of 400 highway miles per week, at that rate you could save as much as $1000.00 per year on gas, not to mention the 31% reduction in RPM. Your new 518 will have automatic shifts into overdrive and lock-up, no toggle switch needed. Now with adjustable vacuum switch. "

 

Come on guys...nobody has tried this kit?

 

any more info?

 

I run their MegaViper transmission, but not that.

 

Here's the link, it only 4 parts and they claim you get and AOD outta ya 727.

You need to re-read that. Look a little further down and there is a photo of what your getting for $85.00, that's to control an OD/LU transmission you need to complete the conversion...

if i remember correctly that is for a gasser. The 518 in the diesels don't have a lock up converter.

 

The article says it can be made to work with a diesel with or without a vacuum pump and/or regulator. I wonder how hard it is to find a non-lockup 518.

 

I gotta admit, I really don't know much about these 727's. So its not possible to do this with my tranny?

 

This is copy/paste from PATC;

This is how to replace your three speed transmission with a 1995 back A518 overdrive transmission with a three wire connector (gas). A 518 transmission has a 31% overdrive and will produce a 30 to 40% increase in gas mileage on the road over a three speed transmission. Remember overdrive is only 3rd gear high range anyway. There are two wire 518 transmissions out there, these have a non-lock-up torque converter. With this three wire setup you have a four speed transmission plus a torque converter lock-up feature. The extra gear is 3rd high range. We've been asked this question for years, so I decided to put it down in black and white. What we're actually going to do here is control the overdrive and torque converter lock-up normally controlled by the computer using one vacuum and two oil pressure switch. Instead of using an electronic speed sensor and throttle position sensor we will use a mechanical / hydraulic / electronic speed sensor and a vacuum / electronic throttle position sensor.

There is no OD on a 727, so it is impossible to do if you have a 727. What this is, is a how-to transmission conversion on adding an OD transmission with lockup torque converter to a vehicle that previously did not have OD with LU converter.

They are not converting a 727, they are converting a vehicle that had a 727...

 

What they are referring to there is using pressure switches to control OD and LU converter in a vehicle that previously did not have OD/LU. Just like everyone already does with the 47RH. You have to have an OD and LU to control OD and LU! These are control options other than a stand alone control which is expensive.

Gasser 518 were built both lockup and non lockup depending on application. Diesel 518 91.5'-93' is non lockup.

 

My thought was, you can't run a vacuum switch on the diesel, so it would be simpler to run a non-lockup 518, because the vacuum switch is being used to control the lockup.

 

They are using hydraulic pressure switches using the various pressure ports on the transmission, as shown on the PATC website there.

The 1991.5-1993 Dodge CTD is non lockup. This is simply pointing out a way to control lockup and OD if you were to put a transmission with lockup and OD in a vehicle that previously did not have it, or have the OEM computer etc to control said LU/OD. Or you did not want to buy an expensive controller for LU/OD.

The vacuum reference is mostly to point out that Ford and GM folks have benefited from conversion swaps and used vacuum control switches because the Fords and GM transmissions are vacuum modulated. Chryslers are not vacuum controlled. They are either hydraulic or electronic controlled.

 

Yeah, I guess their talking about replacing the 727 with a 518. He shouldnt use the word "convert", it throws people (me) off, who dont know anything about these trannies. The advertisement sounds like you can convert a 727. He got me good!

On the diesel side, they are kind of confused about what trucks have what trannies. They insisted my truck had a lockup transmission when I was ordering from them. If I hadn't purchased my TC & VB ahead of time, I probably would have went with their 618 transmission instead of a 518.
