I don't know the difference between the at and mt, but have a thought I will throw at you. If you know your 94 has been taken care of, I would suggest staying with your pump. You can upgrade it with delivery valves, yours have 131's and the later pumps have 181's. A 3,000 govoner spring kit and afc spring kit, advance the timing to 15. My 94 is putting over 400 hp to the ground with original pump.<br>Michael

1ST CUMNZ:<br><br>Welcome to the website!!<br><br>&quot;Michael&quot; has given you good advice on the pumps!<br>The pump you have with the automatic trans. is<br>&quot;rated&quot; at 160 H.P. If you were to buy a 98' (manual<br>tans. pump) it will be &quot;rated&quot; at 215 H.P. The big<br>difference between the pumps is primarily in the<br>pump cam. However, your 160 H.P. can be made<br>to really put out the power! Piers Harry @ &quot;Piers<br>Diesel Research&quot; (1-866-888-9396) is has a<br>&quot;modification package&quot; which will make your <br>truck FLY!! You can call him for details.<br>The &quot;215&quot; pumps can be expensive. I have<br>seen them in price ranging from $1500.00 up<br>to $2500.00. For alot less than that, your<br>&quot;160&quot; pump can be set-up to run very well.<br><br>--------<br>John_P
