I want to talk about transmission coolers for a minute...So, i drive a 2004 silverado crew cab with the 5.3 4x4 z71. I've got the cold air intake, the headers, exhaust and all. i'm eventually going to drop a cam in it and probably a slightly bigger stall. BUT my first priority is keeping that trans cool!
So i'd like to talk with you guys about transmission temps and coolers. im wanting to get a bigger trans cooler than the factory one. (mostly for dyno purposes where theres not a lot of air moving besides the engine fan and the little fan they put down...) because i really dont need a bill for a new transmission... now i know theres a lot of them out there but i want your opinion. has anyone tried the inline aluminum fin ones? single pass? double pass? anybody doing a big one in front of the radiator and maybe and inline one somewhere else for extra cooling?
Also, can you have TOO cool of fluid? from my understanding, besides keeping everything oiled, the fluid also acts as hydraulic fluid in your solenoids? would being too cool effect the performance of those?
Thanks in advance for any input you guys have!
My 1999 Silverado LT has 300+k miles and its got a temperature problem I'm worried about. Running down the highway at 75 the engine temp soars to about 235 but normal temp at 65 and below is 205-210. The temp comes down once I slow down but worried about it being a precursor to a larger problem. Also, the tranny runs at about 210°F when its warmed up and will start rising to 215 if left to idle. Everything I've read says it should be about 175°F. Any help would be appreciated
I currently own a 2013 Suburban LS 5.3. It has the code KNP transmission cooler. I want to add additional cooling for the transmission as I have see temps in the 240 deg range when towing my 4000 lb camping trailer over the various mountain passes in Colorado. I have read virtually all of the threads on here dealing with adding an additional cooler to my burb. I am certain I could add an additional cooler with ease. However I am a believer in the KISS principal and am looking for a larger replacement cooler that would connect to the existing factory oil lines with out having to modify them. If anyone has found a cooler like this I would appreciate hearing from you.
