bad slipping and high rpm shifts

[stickysilvertbird]

ok well.. i have a 95 MN12 with the 4.6.. etc yea. well i havent done a tranny rebuild yet and im sitting at a little over 115k. recently my trannys been acting up. even at normal accel. it takes sometimes 3.5 grand or more to shift from first to second. any gear after that is fine. also when going throught the low gear shifts (i.e. manually shifting 1L-2L-drive.) it wont take off for crap. my tranny bitches and complains all the way to third gear and then its fine. i love the AODE or 4R70W which ever its got in it but i just cant figure out whats wrong . ive checked fluid levels and the shift regulator and both are fine. i would run the codes but no one around here runs OBD-1. any help would greatly appreciated . thanks guys

Some in this forum have had good luck using Sea Foam to clean the transmission and then flushed and filled with new fluid and filter. Don't forget to drain the torque converter at the same time. Check out the Tech help thread at the top of the threads.
