Hey guys. I just put a 350 in my S10 and didn't do much with the existing 4L60E tranny because it was fine prior to the new motor and only had 88k miles. I put new performance OD and 2/3 servos and a bigger boost valve (along with a new filter of course). The fluid level is fine but looks a little darker than new fluid should. Any ideas why I have no reverse? It just acts like it's in neutral when I put it in reverse...I haven't re-dropped the pan yet to check it out, mainly because I have to take my exhaust back down which is quite a PITA!

 

Could this just be a little piece of dirt or rust? I was as careful as I could be but I did the work with the trans under the truck so some dirt could have gotten in...

 

Is the shift cable adjusted properly? Try disconnecting the cable and shift the tranny into reverse by hand. Then start the car and see what happens.

 

It is linkage not a cable. I can hear and feel the definitive click between each gear. The drivetrain is offset to the right for proper fitment in my truck so I had to shim the bracket where the linkage bolts to the frame with a couple washers btw bracket and frame. Like I said though it appears to shift like it should...

 

Bump for ideas!
