4BBodies OP mopar addict 4 Joined: Oct 2005 Posts: 708 Mechanic Falls, Maine	........I finally got to test drive my '73 Roadrunner, the trans was rebuilt by a good shop with a TransGo kit, I have 17 pints of fluid in it when in Neutral, at idle. It is right at the top line. When I tried it, it went good in 1st, but didn't feel right when it went into 2nd, and when letting off the gas felt like the brakes were put on. Is it the front band adjudtment? From what I have been reading it looks that way, I need more input. Thanks!

The rear end turn perfectly in neutral, the brakes are not binding. I just don't know where to start on backing off the adjustment, if that is it, a 1/4 turn? A 1/2 turn?

He is good, he would probably fix it, but getting it there would not be easy, it is still gutted, in the middle of the restoration, and not on the road. I am going to want to try fixing it myself, just like every other stupid little Mopar problem I have had in the past year with the car. The front band adjustment is behind the front cooler line fitting, correct?

Then you are sure you are in the right place and can move on from there. http://www.moparts.org/Tech/Archive/auto/4.html Also check your KD rod adjustment. It should be as far forward as possible and start moving as soon as you start opening the throttle. I had one that shifted REAL late and the front band had backed off since I didn't tighten the nut down after initial rebuild.

This is not an accurate way to test , have you actually DRIVEN IT ??? Is the problem the 1-2 shift or the 2-3 shift , letting off the gas is not the way to test the shifts . running up my post count some more .

And I held the throttle steady. It isn't the KD, as I spent hours getting that right with help from guys in here. I am going to try backing off the adjuster, thanks for everyones input.

My next question is where I can put a drain plug in my trans pan, seems like a logical thing to plan if I am going to be taking it on and off...........

It would make things a whole lot easier for me if I can drill a hole to drain it.........and then put the plug in after. I can weld and then solder the plug. I will call the tranny guy tomorrow too, he might even come out here, he's a great guy, and has a long history in this area.

If you never got into 3rd and backing off the throttle in 2nd felt like the brakes were applied, the problem isn't with front band adjustment but it could be the rear band adjustment. If the rear band is dragging you won't notice it in 1st gear but the drag will bind up 2nd gear. While you have the pan off take a hard look at the rear band adjustment and the condition of the servo and its spring. In many cases, after the installation of a Transgo kit, the heavy rear servo spring will overwhelm the tin retainer and the spring will maintain constant tension on the band causing drag in 2nd and 3rd gears.

Quote: Since I don't have a lift, and also since I only want to get messy once, would this drain pan on Ebay work allright? don't get a chrome pan , if you have an old nasty oil pan rob the drain plug from it . the spot st. louis has it in is under the dipstick.

I won't get to play with this until Sunday, I will re-post what I find after I get the pan off. I need a NEW, CLEAN tub, I want to re-use the new fluid I just put in!

Below is a pic of the stock spring on the right and the heavier spring on the left supplied in the Transgo kit. The stamped retainer often isn't up to the pressure from the heavy spring but sometimes the problem is simply a failure to properly install the snap ring that holds the retainer. 5170930-Rearservosprings.jpg (21 downloads)
