[Tf175]

Shifter update , checked trans fluid level yesterday morning.  To my dismay and embarrassment the fluid was just touching the stick . Three qts ATF brought the level into the safe range . There were no shifting problems during the 700 mile trip home . I should note that the trans always shifts/pulls well , the shifter is actually a gear selector . When we had problems Friday ( mostly the N to D shift ) it was very hot and we got stuck for hours in a traffic snarl on I 65 N at E Town ,Ky . Perhaps heat soak compromised fluid pressure to shifter . We were also experiencing an overheating problem,  about which I will post another thread .
I have found T. Anderson to be a very good outfit . Sourced information and parts from them when I went through the gear position indicator components .
Thanks for the input !
