LOOOONG TF Shifting issue.!
« on: July 27, 2008, 11:14:28 AM »

The shifts in the Torqueflite in my Sport Fury take a LOOOOOONG time to complete. Under normal acceleration, the 1-2 and 2-3 shifts seem to happen at the right time, but are really slushy. With more 'spirited' acceleration, the shift issue is worse.

The fluid is clean, at the proper level and has no burnt smell. Once in gear it doesn't feel like she's slipping, but I could be mistaken I suppose.

Before I start getting bummed out about a trip to the transmission shop, could this be a misadjusted linkage problem? Seems to me I read about the linkage being directly responsible for the shifts.

Any help is as always GREATLY appreciated.

Thanks and standing-by,
Uncle Hulka

I'd spend ten bucks and put a fresh tranny filter in it first.  My 383 4V Polara acted like this shortly after I bought it and that's what cured it.  It had bright red tranny fluid too...

Yup.I am with Matt.Do a splash and dash,filter,flush and gush.
and adjust the kickdown linkage as per FSM .
Remove the little service cover on the bell housing and drain out the fluid from the convertor as well. I believe it is a 5/16"  or 1/4" wrench you need for that.

Do as advised...simple tranny service...and then you will need to adjust the kickdown linkage...sounds like you have just a touch too much throttle pressure...the more throttle pressure you have the longer it will take to shift between gears.
 
I usually have to fiddle with my sdjustment over a couple days of driving to get it set right where I want it.

There will be about 9 quarts of fluid coming out of your pan and converter.  Use a LARGE drip pan.
 
I agree with the above.  Clean fluid will not tell you whether your filter is clogged.  Also, a toroughly clean, but non-adjusted transmission is not going to shift right.  Do adjust your bands and kick-down linkage.

You see? This is why I love this place!!! I would never have thought of a dirty trans filter. And the torque converter can be drained while installed? Brilliant!

I am more than a little nervous about adjusting bands. I have a FSM that I assume will outline in detail what's involved. Are special tools required?

MoparMatt, I don't know how long the car has sat, but it appears to have been quite awhile.

CBarge, are you talking about the gasket on the torque converter drain plug?

So my shopping list will consist of:
10 qts. of ATF+4 Fluid
1 Trans filter
1 pan gasket
1 torque converter drain plug gasket (?)

If I am forgetting anything please advise.

Thanks for the great advise. I will post results ASAP.

You don't have to adjust any bands, just the kickdown-linkage at the carb.
This linkage and it's adjustment is very important to the correct workings of a Mopar automatic transmission. It controls for a great deal the oilpressure inside the transmission and the shift-points.

You mentioned earlier the oillevel is "correct".
Now, I've heard folks say that before, but they didn't know a Mopar transmission's oillevel is checked with a running engine and the transmission in "Neutral". And NOT in Park, like all the GM-transmissions in cars usually.

Good luck!

They are all right.  But I would suggest a band adjustment anyway.  You don't have to do it, but they are subject to wear and who knows when they were last done.
 
A proper adjustment will make them last longer.

While you have everything apart install one of these babies....

A drain plug for your 727 tranny pan...makes future servicing SO MUCH simpler and cleaner.
 
I have installed these in every one of my trannies since I discovered this item some years back.  I usually install it on the pass side front corner of the pan...about a inch or so in from the side rails.

I put one on Polaraco, but brazed it in.  Mine is in the rear near the bottom of the pan.  Unfortunately, I don't have a drain in the converter.

These do make changing the fluid much easier, but it also makes it easy to not change the filter.  It's a matter of preference, but I would not use one.  I think the lack of a plug on most car's trans pans, regardless of make, is to prevent the possibility of not changing the filter.
 


Not a good idea.
 
My opinion.

BigBlockMopar, I'm hip to checking the fluid in Neutral and not park, but thanks for the tip.

A friend at work suggested adding the drain plug. Your posts convince me it's a smart thing to do. Snotty makes a good point that it is a shortcut that could be abused.  Thanks for the 'word to the wise'!

I will begin by making sure that the linkage is properly adjusted (per the FSM). A fluid/filter change will be done regardless.

I will share my success/failure with you all.

Thanks for the priceless aid!

The gasket that I am talking about is NOT for the convertor.
The said gasket is a Mopar dealer piece.It is used on the tranny pan of newer style overdrive trannies in the Ram trucks equipped with the A518 (which is an OD727 unit.) It fits older 727 units.
Worth the few extra bux and seals up much better than the cheapo cork or black gasket that comes in a filter kit,IMO.
I do not have the Mopar part # but I can get it tomorrow.
