If i pull away in drive, trans will up shift 1st & 2nd ok it will not go into drive until iam @ 40-45 mph, now still in drive, when i reduce speed to around 20 mph it will down shift by itself into second gear, speed up again to 40-45 mph it will go into drive, its not sluggage or any thing like that, manuel shifting good in first 2nd gear will scretch tires and into drive fine but iam after surpassing the 45 mph by then. just want to make sure every thing is fine,,thought maybe passing ing gear leakage may be set a tad back to far, or shift kit may have been installed or valve body something done like that, to the way of its behavour or responce, i did not have the pan off or looked inside of this tranny because the guy i got it of didn't know to much on the internal stuff but said it was working fine.the tran sat in a heated barn for awhile i put new fluid in it, and will be changing the filter soon the touque converter suppose to be a little higher then a stock converter, its 440. thxs tactransman looking forward to your repley ..
