I was told by the transmission shop that if they installed a stall convertor (I was considering a 3200) that it would set off the check engine lites and won't pass a N.C. inspection. Fact or fiction?

Fiction.

I was told by one my TCI3500 would NOT help my car. FICTION. He did fix the valvebody in my Bravada for cheap though.

ive never heard of converters triggering trouble codes OR failing emissions.. and i once had a guy tell me a stall converter wouldnt help my car either....

i had a guy tell me a 224 581 112lsa cam wouldn't "lope" without a converter...fact or fiction?? hahaha

It sound slike the guy doesn't want to do the job, and is blowing smoke. I would take your ride somewhere else, where it could be appreciated.
Oh yeah.... FICTION

The only cars having SES lights with converters are usually the 01-02's. I have a 02 and ran a 3600 with no problems. I have a 4600 now and do have a slight problem with code P0757 but its normal and just needs to be removed via Edit. You won't have a single problem with your 98. The guy is talking out his ***.

I think the Code is thrown because of the TM sys. which is easily deleted. Good Luck

I don't think its a TM issue. If you run a search on P0757 you'll find more information about it. The code is set under certain conditions. One way to avoid it is drive in D while under 50MPH and then goto OD after 50 MPH. So far this has cured my problem till I can get my tune done.

I really think it is necessary for all 01-02 F-Bodys to delete TM after installing a higher stall converter, isnt the P0757 a result of the slippage of the converter.

I don't think it's a must, but it def. makes driving/shifts feel better. The P0757 was about something like the constant locking/unlocking the converter confuses the PCM or something. I'm not too sure man. I could pull something out of my *** right now but then I would look like a idiot

As far as my 4600 and TM, i surprisingly don't have too many problems with TM. I can def. feel it on shifts though.
