higher stall speed higher fluid temp?

[grumpyvette]

I recently just replaced my trans (A4) to an RPM trans with a 3000 stall converter. The trans is running around 217F degrees and the air temps are not even hot yet. I do also have a separate trans cooler after the radiator. Does this temp seem normal. Stock it always ran around 190F degrees. Thanks for any input.

no its not normal, but it is rather common, with a high stall speed converter,being installed, you need to find and install a more effective trans fluid cooler or youll find that higher average fluid temp will reduce the transmission life span noticeably, lots of guys ignore this and find that they eventually need to replace the transmission, they get it rebuilt, replaced and the new trans doesn,t hold up for the same reason the original trans failed...the trans fluid is too hot!
rather than find this out the way many guys do and pay for several transmissions its smarter to instal an effective trans fluid cooler with a fan, and AN# 8 lines to the cooler

be sure you accurately measure the available room in the location you plan to install an aux trans fluid cooler , get as large a cooler as you can fit in the car with a powered fan, because keeping the trans fluid down near 170F significantly extends trans life
