Do you want the 88-93 or 94-98 grill?  I may know a guy that has a new 88-93 black gmc grill wrapped up in the garage

Hmm....

Thats a good question! I have the later one here that needs paint and a billet insert. However, ive never seen a non-chrome early one.

I'll need to find some pictures....

If this tank is to be believed, 16mpg!

Im guessing it's a fluke somehow.

Not a fluke. 16.6 miles to the gallon this last tank. My guess is that the shorter tires get it into the sweet spot of the RPM range and also that tightening up the exhaust reduced the amount of air leakage prior to the oxygen sensor making it lean out a little bit. Regardless of whatever reason I am taking it as a berkeleying win.

Hi Michael, sorry for disturbing this thread while it is in slumber, but I have a couple of questions about the 4L60E trans. 

 

We are in the process of building a custom order vehicle and the customer supplied a LQ4 Vortec fitted with a 4L60E, and we have to install it, with a trans cooler. 

Now the thing is, here in South Africa, the most common auto box that is still used by many of the V8 guys are the old tech Th350, so when asking them, they say that, either a cooler is not necessary or they recommend something like this

 

I was wondering if either you, or anybody reading this, would be able to help with the pressure rating of the transmission on the out put to, and return from the cooler, and a recommended size for the cooler. 

Or if anybody can help with a workshop manual, I would appreciate it.

If i get a chance today, ill pull out the factory shop manual and see if it has specs. 

However, i can do some practical information. 

The 4l60e cooler in the heavy duty application used the radiator cooler and a plate style extra cooler of roughly 8×12 inches plumbed in series. Fluid went to the external, then internal cooler then trans. 

As far as pressure, it's not really any different than the th350. A bulge on the end of the hardline, normal hose and hose clamp, and done. 

 

Hope this helps.

This truck just continues to be awesome. Does truck stuff well, and rarely needs attention. 

I love this truck. 

Due for an oil change and nut and bolt check. Otherwise, keeps on working!
