I have a 1993 f-250 4x4 225,000 miles Its a good old work truck. but shes been feelin a bit neglected lately, Runnin rough and smellin of raw fuel so i ran a diagnostic test, did not get the results i expected. KOEO codes are 621,622,624,626,629,634,637,654. all transmission related has anyone seen so many codes at once. Scanner wont let me run a KOER test untill i fix tranny . (one side note) Ever since i have had truck she does want to pull off in 2nd gear must leave in drive . thanks hope some one can help

it happens , dont worry about it
now to the problem
with all it shows wrong you may have a ground problem
there are several grounds that are common to many sensors and solenoids
also check all connectors
the mlps is mounted to the shifter in shaft and is known to cause problems
such as what you have

go to down load files and look for the article on mlps
this can cause the running rich on its own
