To install a temp gauge for the tranny, where is a good place to put the sending unit?
Most aftermarket trans temp gauges mount the senders in the line pressure tap. This is the best location.
As an alternate, the output line to the transmission cooler is good.
(a) This may seem like a REALLY dumb question... but don't you HAVE a [rudimentary] trans temp gauge? We had two new 6.0L/4L80E Chevys in 05/06, one 2500HD Silverado, one 2500 Express Cargo. KNOW the Silverado had one, was pretty sure the Express had one too?
(b) If not, don't forget AutoMeter makes a nice temp sending unit "block" for like $25 or something. Check www.summitracing.com
(c) The second location Steve mentioned sounds the easiest - I'm assuming the hard line just before the radiator? Steve what exactly do you mean by the first location? Does the 4L80E have a "test port" on the side like the 4L60E which is perfect to thread in a temp sender?
(d) Finally, I'd assume right in front of the radiator (or slightly below) is the best place to mount the cooler.... but to make up for the blocked airflow to the radiator you might want to consider a dual-fluid cooler (i.e. engine oil / trans fluid). Or maybe you could mount the cooler anywhere if you got one with an electric fan attached, but to me that's too complicated with the fan/electric hookup...
(e) Good luck with the Express. We really liked ours. Except the mirrors sucked for towing an enclosed trailer.
