new tranny install

[Longhorn Man]

normally, an overdrive tranny with a poorly adjusted TV cable will last for 25,000 miles, and THEN it'll crap out. Soime guys who have adjusted it 'by ear' have had it shifting just right (seat of the pants) and were shocked to discover it was wrong 25,000 miles later.

Now, in the shop's defence.... In a stock set up, there isn't much reason to check out the line pressure. It's a good idea, but not really needed. Becouser of this, some shops aren't aware of the importance of adjusting it while watching the line pressure. After market intakes, carbs, and brackets make all the variables jump into your face and that's when the damage happens.

While there probably is a little added wear on your tranny, think of it more as like the wear on a tire. Sure, spinnong the right rear a little bit going around the corner DID leave some rubber on the road, however, you can look, inspect, measure, and complain, but in all reality, that right rear is still a brand new tire, and the wear put on it is minimal at best.

My opinion on this, would to say do it yourself. Non stock aplications call for added caution, and onless the shop you pick knows what you are talking about, they'll just agree with you pretending to know what you are talking about, (becouse shop owners LOVE to hear how things work from a customer) and then they'll go and do pretty much the same thing trannay shop #1 did.
You can check out bow tie overdrives, and get the kits they offer. ONless you have a quadrajet, you should probably go ahead and get the kit that has the throttle bell crank in addition to the kit for adjusting the cable.

I know it'll set you back a little more money...just as you thoguht you were done spending on it, but IMO, this is the ONLY way you'll KNOW it is right. (if the hands on part is a little above your level of work, I'd get the kits and there is bound to be a gear head around at work or even a local board member who will help you out, maybe at the cost of a 12 pack or so)
