Is swapping the tc in my 727 a wise idea or will the stocker hold up fine???
My engine/trans has 400,000 kms on it but I'm not sure if the trans is origional or not.
Will this give me an appreciable mpg gain or should I just wait and upgrade to a 47rh later?
Anyone done the converter on their 727 and see a big difference or if you did it again would you do something differently?

I'd recommend a swap. Not sure if the MPG gain would pay for it, but I know of guys who claimed a 4mpg increase with an aftermarket convertor and some valv ebody adjustments.

torgue con is a good idea a properly built 727 is industrucable,find someone who builds trans for drag /hot rods this trans was put behind 426 hemis and all kinds of drag cars and were faster than 4 sps. people that tell they are junk prob.never owned one or drove a worn out stock trans

 

How much torque is a 426 Hemi capable of? I was under the impression it was around 500-550 unless you did some real hopping up. Not to say the 727 wouldnt hold, but a 400hp gasser is MUCH different from a 400hp diesel.

The 727 is byfar imo the best auto dodge ever made. If I hadnt been itching for a stick Id have stuck a gear splitter behind my 727 and slapped a torque converter in it and called it good.

 

Sounds like a concensus to me fella's! I just spoke to Mark at Hughes and the price and advice are good so I think I found my vendor. Far away from Canada though.....
Mark says that I should check the contents of the pan before I jump to any freshining up conclusions. I sure do appreciate people out there who are honest!!

 

I have mine prety hoped up and my 727 is holding up great stock. Where would i be able to find a tc upgrade for mine? The only problem ive had with mine is not being able to go faster after it hits the last gear. Its kinda anoying but i love my truck so who cares...

 

You need 3200 RPM spring.

 

if i put in a 3200 rpm spring wont that kill my motor faster? i mean i know the new cummins motors rev up that high but can my motor handle that?

 

The 3200 spring will give you a little more RPMs before it defuel's and it makes it alot more driveable. I couldn't be happier with that upgrade I felt the difference instantly and I also have the 727 auto in a 4x4. DO IT you won't regret it, and by the way it's pretty cheap and easy to do.

Only if you insist on driving 100 MPH all the time.

 

ok that sounds good. But how do i do that? i mean i can figure a lot of this stuff out with some guidence i work on big rigs all day mostly cat and cummins in dump trucks... but please give me an idea of what i would have to do to make it rev that high? Thank you, all of you are very helpfull and knowlegable i really appreciate it cause my truck is my life.

BTW it sounds ALOT harder to do than it actually is

 

man that looks good to me but now the hard part is finding time to do it thank you once again

 

It honestly only took me about 45min to do. They say the first time always takes the longest.
