A 3500 converter is fine with a stock engine/trans. Absolutely - lots of members here have such a combo.
However a bad converter might give such symptoms; I don't have any experience with bad converters; hopefully others can post their knowledge and experience.

Local shops will freak out when you tell them you have 3500 stall converter. They mostly have no idea of LS converter technology and what makes these cars run.

What brand is your converter? Did you buy it new or used?

You're in Texas, there are many LS shops in that state. Stop going to that trans place, they have no idea about LS setups.

Just to name 2 even though they are in Houston, LMR and G Force motorsports. Try contacting them and maybe they can refer someone closer to your area.

Thanks for the names. I've called many shops and a few big name builders but they can't help without seeing the car.

I just got the car dropped back off at my house. What's wierd is the tow truck driver mentioned I had no reverse. But the forwards were fine. Every time I got in it, reverse was strong but I didn't have forwards... I still don't think this is converter related. I did just pick up a cheap stock one tho just in case.

Found a cut wire on the VSS. Stupid shop can't check fluid levels and basic electrical connections. Car runs awesome!
