I have confidence my truck will last another 3 years pain-free. Transmission is more of the heart of the truck than anything else. Everything else can be replaced piece by piece, less the engine block

With regards to this chart...this is if you are operating your transmission in those temp ranges 100% of the time! Seriously, how many people do that? Even with our stock tranny cooler? Its a bit deceiving to the public to use this chart in such a dishonest manner. Lets get real and stop with the fear mongering and recommending a second tranny cooler. Like I said the factory one is sufficient in itself. According to my scan tool I run my tranny between 145 and 175 on an average day. We dont want average every day folk going around worrying about something that really isnt as important as changing the fluid itself.

Total damage: $3,118.67
gmcman said:Whatever trans you go with, I would make sure it has the GM hardened sunshell and not the "Beast"... reason is the GM is a more balanced unit.
CaptainXL said:I don't see a problem. The members over at the full size chevy forum recommend the "Beast" all the time. You might want to let them know.
DenaliHD66 said:A few things I've noticed with the new tranny so far:
1. On a cold startup, sometimes the truck will lurch forward in place.
2. When shifted with the brake fully depressed into drive, there is a significant clunk.
3. When shifted into reverse with the brake fully depressed, there is also a significant clunk.
Could this be an indicating of too much play in the u-joint or something not hooked up properly?

gmcman said:OP went with a Jasper from what I can tell, I don't think they rebuild, only reman.

DenaliHD66 said:Okay cool, so anyone know since the tranny cooler lines bypass the radiator now to their own dedicated cooler, will the radiator fluid run any cooler than normal?

CaptainXL said:No. The coolant usually heats up the transmission faster. Your efficiency is gonna get hurt in the winter using a dedicated connection as the trans fluid will take longer to heat up. Would be better to connect both the radiator and external cooler in series.

HARDTRAILZ said:Interesting...a few posts ago, you were against external coolers. Why the change of heart?
CaptainXL said:the fluid temp ranged from 210-230F.
CaptainXL said:Coolant temp stayed steady at 210F.
CaptainXL said:I was towing my 6000 lb trailer the other day up and down hills going 60 mph and the fluid temp ranged from 210-230F. :
CaptainXL said:You shouldnt tow over 50 mph with a full load. Did you know this?
jonbo2002 said:sounds like talking out both sides of your face is becomming your deal! you tried telling me off like I was a dumb ass for towing 60-65!!!
Playsinsnow said:Hmmm. When did a 6,000lbs trailer become a full load?
I have 3.42 gears with a swb 4.2 and a full load to me is 10,000lbs GCWR.
Not sure about speeds because it depends where I am towing.
Am I misinformed?
I won't pull a 6,000lbs trailer but those that are rated to it should be at full load when GCWR is reached? Hypothetically of course, if all variables are appropriate and present?
Playsinsnow said:I am aware of the different weight ratings between GCWR, trailer, and cargo. Guess I expected more from an XL/EXT. Is the curb weight difference really only 300lbs (don't remember where I read) between an ext and swb? Assuming both are 2wd or 4wd of course.
Sorry for the thread jack too.
I second the aux cooler after the factory for same reasons.
jonbo2002 said:actually the 10,000lbs applys for the swb and ext as long as they both are 4.2 with 4.42 gears. so the swb can tow a few hundred pounds more, being as it is a few hundred pounds less.
Playsinsnow said:$20 says you meant 3.42gears...
There has been discussion elsewhere that GM sets conservative max weights for towing? I couldn't imagine trying to tow more without serious mods.
