Doing 5.3 vortec with 4l60e trans and had the trans rebuilt to basically a race spec tranny minus servos to prevent hard shifting. However when I fired it up this weekend the tranny did not really shift into any gear. I jacked up the rear end and when put in reverse still wants to go forward in neutral and drive it goes forward but I can grab the driveshaft and stop it by hand. Checked for output to cooler and only get about a 1/4 quart in a min. Called my tranny guy and he is headed out here on Tue. Just wondering what you tranny guys know or if anyone has seen this before.
