Question: pressure

[malibu795]

It can help a stock trans but I worry what will happen with the converter clutch lining if it's stock. Temps might go slightly higher.

From your opinion on my 115-120° cruising temps in 30-40° ambient air, I have a rather large temp cushion. Summertime 80-90° air temps tranny runs 140-150°

Off topic a little Mike, but can an Allison be built to hold up in a pulling truck at 1200hp? Seem's almost everyone changes over to ZF6 at that hp pulling.

Thanks for ignoring my question Mike! :thumb:

Wasn't ignoring you. Remember I have a business to run and I'm on and off here while I'm doing it. I'll answer later.

I started my own thread if you would like to respond there.

Thanks!

I have no experience in sled pulling and don't know which trans would be better. I've built a bunch of Allisons and set them up for sled pulling but don't know if a stick shift is better. My transmissions have done well is all I can tell you.The trucks won a lot.:dontknow:
Sorry but sled pulling just doesn't interest me.

From what I've seen. You can run a stock trans if your just pulling it. I do have the spring in mine to boost line pressure. Three seasons on it so far...

Hey Mike l does running your spring and shim have any adverse effects on the trans

 

[lawnboy01]

This is on a truck that gets zero road miles. My trans has 433k miles on it. All I'm running is ATS converter, ATS spring and little cam thingy, and DHD lock up box. I honestly couldn't tell you if there are adverse affects on the trans. And I do 4th gear starts

So far so good

None whatsoever.

 

[forkman]

Mike l what do you charge for the spring

 

[forkman]

Can you tell a difference in a 450-500 hp truck

Call the phone number in his signature and he'll explain it to you in great detail. Honestly. I would recommend his spring also, but seriously, you'll learn more by calling him.

Hey Mike,
At last pull I smelled clutches. Pressure is at 275 and hp is 750. What should I raise it to when I freshen trans?

Use 2 shims. Make sure there is no knock down. What kit are you using and what converter? Is the converter locking when it should?

Single sided GMAX

Looked good in log

Get rid of the single sided clutches. Suncoast has better stuff now.

In all clutch packs or can I do C3? If all other clutches look good.

C3 is where you don't want them. They hold up fairly well in c4 and of course in C1

I would not use them in a 6 speed C4 clutch pack in competition.
