Nothing wrong with a good C-4.

C4s are just so hit and miss.  They seem to break so often if you have good power that requires some RPM.


Mine doesn't break, but it loves pissing ATF on the driveway.  Undecided

Ever since my trans guy modified my C4 the last time a few months back it has stood up to my 408W and my driving style.  My race weight is 3800# (weight and rpm makes a big difference in longevity).  I was shifting 'bout 6800rpm at the track and 'bout 6500rpm once in a while on the street and for sure 6000rpm lots of times everywhere we go.      Naughty

the downfall to the aod is the tv cable depending on valve body and from what Ive done with them no matter how much you firm up the 1-2 shift, theres a delay. this was a huge part of my decision and I talked to a few different people about it and there is no way around it

what is the exact application?

Side note, have you checked the o ring around the dipstick tube? Mine was missing and I chased it forever as an oil pan leak.

A few months? I would wait quite a bit longer than that before I judge the success of something like this.

the low first gear is kind of useless unless you are going to run 3.27 gear or something. at that point there isnt as much need for OD

My c6 has a 2.72 first gear.

Rear end is 4.56:1

29 inch tires.

1800rpm stall.

Idle to 4k powerband in a 347

Lots of torque!!!!

First gear is nearly useless unless climbing a hill or something similar.

It cost some money for a built AOD but once done they make a good trans. If you use a man. valve body, no need for TV.

depends on the set up for sure, it works for my mild 302 in the LTD, but if I put this 418 in the same car it won't be ideal, then a 2.40 would probably work better.

I hear what you are saying.

Just in the past after I got the 408W up and running the trans would start doing it's flare-slip dance at WOT going into 3rd gear after just one month and it would progressively get worse after that.

It's been three months now and it is still shifting WOT into 3rd as hard and fast as the first day that I got it back from my trans guy.

Robert - does your transmission guy charge you for all these rebuilds or is it a warranty situation?

The reason that he has been and will remain my trans guy since 2000 is because he hasn't charged me a dime more for those recent rebuilds.  He honors his warranty.

Not many cool business-type mechanics like him anymore.  The norm is to get screwed over and they like to blame the driver or the engine or something else besides themselves ...

That's good to hear. 

When I was pricing out automatics for my build - I could not get ANYONE to give me a warranty on a C4.  I had several shops offer lifetime no questions asked warranty on TH400s, Powerglides, C6s and AOD/4R70ws.

The last guy I used told me that C4 parts were getting harder to find.  That may have something to do with it.

I think it's Nathan's power level.  My trans guy wouldn't warranty the C4 if the Merc had 1000HP, either.  He would tell me to put a PG in it.
