Question: With the recent postings about the L's losing boost when the trans fluid gets hot, should we be looking into upgrading the tranny coolers?

If so does anyone have some good ones in mind that would work without major cosmetic mods? Any experiences good / bad would be a help...

 

Its not the trans cooler
Believe me, the cooler doesn't shut you down.

 

Hey Roger, Sal here. I was actually planning on posting about this topic soon. I happen to know the trans calibration engineer for the 99 Lightning project, and he told me, "Sal, the first thing you should do when you get your 99, is yank the stock tranny cooler off, and install a much bigger one, it needs it". He was obviously right about that I have been asked about this problem quite a bit as of late, so in the near future I will look into offering a "bolt-in" replacement larger cooler kit. I'll keep everyone posted on the progress....

Andre, one of the failsafes in the PCM strategy monitors transmission fluid temperature (TFT) and if it exceeds a set value, the PCM will shut the boost off. At first, when people were describing the loss of boost concern at the track after the 1-2 shift, I though they were nuts until it happened to me I contacted one of my engineer buddies from the 99 project and he informed me of this failsafe (as well as others). I checked it with the NGS after it happend, and it was correct. It seems to be happening after long burnouts in most cases, and ironically, people are seeing thier best 60fts ever on these passes, which then shut the boost off after the 1-2 upshift. The long burnouts, as well as shutting the truck off between passes, not allowing the fluid to be run though the cooler, keep the fluid pretty hot.

Sal
Just a quick question you stated that it (EEC I don't like PCM sounds too GM) shuts the boost off. Does it not in fact pull timing and fuel? Another reason why I like DFI.

Hi Sal. Thanks for the reply, it contained everything I was looking for <natch>...

Please let me/us know when you get something put together. BTW, just curious, would you know the size of the cooler on the Powerstroke?

 

Hey Sal, That was the answer I was looking for. Put me 1st on the list for a replacement larger cooler kit.Jim

Hey BA, Sal here. I have not monitored the PIDs during the actual failsafe process, because I don't really like trying to MAKE it do it, but what it does is it shuts the boost off via the supercharger by-pass solenoid. The solenoid is in-line with the vacuum source that feeds the by-pass. During the failsafe for TFT too high, it also engages the convertor, to elimiate convertor slip to reduce heat.

Sal just keep us informed about that larger cooler!!!!!!

 

I was thinking of upgrading the cooler with a large unit from the likes of GReddy, or maybe HKS. I was thinking maybe just replacing the lower grill with it, kinda that import/actually functional look. What do you guys think?

Hey Guys,
This is probably a dumb question, do all the Lightnings have the trans cooler? Or just the trucks ordered with the towing package? I think my 97 XLT only came with the cooler when ordered with the towing package.
Thanks in advance.

Jim, Sal here. All the Lightnings come with the trans cooler, even the first gen trucks.

Floyd91,

The lower grill section already has a radiator in it for the intercooler, it is functinal.

 

ugh...thats actually what I was talking about, bigger intercooler. Sheesh I get confused sometimes. I saw that thing down there and was like wow, I thought they were one in the same, but obviousely not. Thanks for clearing that up

Sal do have any idea when a bigger Trans cooler will be available. I have the Bolt tore down & would like to make as many upgrades as possible while I'm rebuilding the Beast. Let me know if or when you think it will be available & price estimates.

Later,
