my 4.44 is acting up...help

[nexus_7]

Bud did my conversion 2 or so years ago, and just last week now it has started having real slow shifts between 2-3 and 3-4. Up reving and what not with out shifting unless I ease off.



I did the trans code check cause the power light was blinking 16 times on start up...but after finishing the code check the power light just keeps flashing I got to about 145 and quit.



What do I do?



Thanks



Greg
