The tranny on my car has 204,000 miles on it with a B&M shift kit that was installed at about 180,000 miles. The tranny makes no noise, and if you have it in Drive it'll spin 'em in second pretty easily. My motor pulls real hard especially after 3000 rpm and when I give it I like to take it to about 6000. The only problem is that the rpm's flare up as it try's to shift into second. Is this because the tranny was set up to shift at the factory redline or is it slipping because of the insane milage?or both?

 

if the rpm goes up not in porpotion to the amount the car pulls the trans is slipping, the rpms should climb at a fairly flat line if you were to graph them not have a big spike

 

Sounds like my car when it shifts into 3rd and 4th

 

When it shifts the rpms should go down not up...
