engine and tranny temps

my td5 has a engine tm 1 and the alarm set at 90c ..it has never sounded even on fraser island. we fitted a new radiator recently though and it is chipped by bruce davis..always seems to run around 86/88 deg when working.:p

Hi Frosty
I also have a TM4 fitted, In driving 30 mins to work over Winter in Sydney the auto rarely made 65, out on the freeway hovers around mid seventies to low eighties. Three weeks ago I took her into the Snowy Mountains and in one massive constant dirt road hill climb of around 600m gained altitude it went right up to the limit of the guage at 128 :eek:, luckily by then I was at the top and in the relatively meandering downhill it slowly cooled down, took a while and I wasnt confident until it went under 100 again - I thought I'd baked the Auto
Ive had this TD5 for 4 years with no major auto problems and wonder wether having fitted the temp guage I have added something extra I can worry about :confused: that didnt bother me before when I went up steep hills
Engine has consistantly never read higher than 95 so at least thats off my worry list

Your alarms are set too low for both, but especially the automatic transmission.

According to Ashcrofts Transmissions, a well recognised expert in the ZF automatic transmission fitted in the Land Rovers - Transmission Oil
Absolute maximum temperature (can result in damage) - 149*C (300*F).
Maximum allowable temperature for short durations such as a hill climb - 135*C (275*F).
Normal operating temperature range - 80*C (175*F) - 94*C (200*F).
Minimum operating temperature - 66*C (once the vehicle has warmed up from a cold start).

Where are you guys putting the sensor for the auto tranny ?, that will affect the reading you get
