So I have a 2001 Silverado 5.3 with a 4L60E in a 1994 S-10. The tune was started by a local tuner, but was cut short due to breaking an aftermarket driveshaft. So here is the deal, when I full throttle shift into 3rd, it's almost like someone throws it into neutral. If I back off, it will engage, and then I can get back in it, and have no noticeable slippage. I have no problems other than that. I know he bumped up the line pressure, but I don't know where that really is in the tune. I am sure he made some other changes too. Can some one tell me a few things:
1) what do I need to post up to have someone point me in the right direction? Just a tune, or a log, if so, of what?
2) If I need to post a log, can you please tell me what and where I need to go to log it?
BTW I have a HPT pro, and have almost no idea how to use it so far.
Thanks!!
