I believe that it is everything behind the flywheel, all the pieces that make the car move in different directions

What if you increased the line pressure? would that help out the clutch packs?
You got me more worried than usual.

LIne pressure, could that be adusted with a simple resistor?

My L-67 actually had a different Tranny kit from Autozone when I changed the tranny fluid. I don know how different the N/A and the SC trannys are, but the part number is different for the filter. I actually had a filter for a 1990 Buick Regal with N\A version of the same tranny it looked different.

Thanks for the replies, guys. This gives me a little better plan for that sad day when my transmission decides to take the big sleep. I still need to find out for sure whether I have a 60 or a 65... there was some debate about whether or not the '97s were a mixed breed. Either way it seems I could benefit from a different TC, if not an entire tranny rebuild.

Hi there all....I just found your website, and even though I don't own a Bonnie, I figure a Rivi is close enoug.

THe tranny issue is something that I have had fitful nights of sleep over as well. Even though the Rivi isn't modded at the present, it will be soon enough.

I found a website that sells products, and i haven't seen it in the site, so maybe no one knows about it. But there is an excellent FAQ section that deals with the trannies of the N/A and */C cars. the link is:

http://www.thrashercharged.com/tech_htm/FAQ-4t65E.shtm

Hope it clears some things up. Also, one of the techs there told me that the stock 4T65E-HD is good for about 330HP stock, although some of their cars have 370HP on the stock tranny.

Why would GM lie about specs but another huge company like Ford tell the truth? I'm a bit baffled. And just to clarify, I'm not trying to call anyone a liar. I think if anything I'm just frustrated that I need a performance-built transmission to handle any serious mods. It'* a pain in the posterior to know I'll have to shell out 1-2k in the next couple years to keep this car on the road.
Not that it'* relevant but it'* actually 235 more HP and 270 lb/ft of torque more than the tranny specs in the 96/97 Thunderbird/Cougar/Mustang(whatever used the 4r70w)... The 94/95 4.6'* were weaker so add another 15 lb/ft of torque to the under-rating. Or maybe it'* vice versa, but the fact remains, that they could even be over rated(especially the 94/95)

Thanks for that clarification BlackBird . I've got another tranny question. I've always been told that when you have your fluid flushed there are two ways to do it. You can either let the fluid drain out, or else hook it up to a machine that uses vacuum to suck all the fluid out. I've always asked for the sucky kind (pun intended), but what is the proper name for that procedure? And is the vacuum machine really better than any other method? Thanks.

Oh, and by the way, I was under the car changing the oil the other day, and there doesn't seem to be anything stamped on my transmission pan. Does this mean it'* a 4T65?

Default Tranny

Actually, It uses the pump in the tranny to flush the entire unit out. dropping the pan only changes half the oil. I do both ways, pump first then drop the pan to replace the filter. costs more .... but alot less than the tranny does......
