Temp Gauge

[CTDsix]

I've Read A Few Post From Manual Transmission Owners Claiming They Do Not Need A Temp Gauge. Why Would A Manual Transmission Not Need A Temp Gauge And An Auto Would? I Want Purchase Gauges Next Week... And I Have A Manual Six... Do I Only Need A Turbo Boost And Pyro?

Thanks,

Ralph

Main questions would be- Do you tow and how heavy? Do you tow in the mountians at all, if you do?



I have heard of some guys seeing over 250*, even on a manual transmission. If transmission temp will be needed, a gauge for the rear end would probably be a good idea also. If you are a flatlander, or tow light, you probably don't need a transmission temp gauge If tht is the case, then boost and pyro.

I have a temp guage on my 01 5 speed... . on an average day with the truck pulling a 15K lb trailer the temp never got above 150* or so. . on a hot day at above 100* outside the temp never rose above about 180-190* both within the safe range of the oil... From that experience I didn't install one on my 04, I just don't think you can overheat it and damage it... . The auto is a different story... above 220* or so and it will fade away into a transmission overhaul... . So from my stand point the only thing that a temp gauge in the 6 speed might tell me is that its got a bad bearing..... from heat... and I'm not sure it would do that... .



Hope this helps... its just what I've seen ... ...

Remember that ATF is a complex fluid. It must act as a coolant, a fricition eliminator, and a friction enhancer. Being so complex, it's very susceptable to heat damage. To make matters worse, it's also the connection between your engine and your wheels (except when the lockup clutch is engaged). All this makes automatic transmissions run much hotter than manuals, whose fluid is simply a lubricant.



If you're worried about your NV5600 temps, pick up a set of FastCoolers from Geno's. They also include a 1/4-NPT temperature sender port.

Fast Coolers installed...hot run thru the desert

After my first failed attempt at installing Fast Coolers (note: use RTV Silicone not gasket maker), and dumping $60 worth of RP, then finding Penzoil Synchromesh... got it all sealed up with 7 quarts and headed south from Oregon. Shifted the same as stock (go figure), and it's very apparent that the NV5600 is a HUGE heat sink in itself. Temperature takes well over an hour at highway speeds to reach maximum. Normal seems to be (unloaded) 195-205F, I did see near 215F during a trek through central Cal, where my overhead read 110F :--)

I'll run the Synchromesh for 10-15K then dump for Redline MTL, then see what the temps do. Just wish I knew how hot the trans got before the Fast Coolers! Oo.
