You can do the key dance to check codes. I only ever got a light for the EGR. The CAT should be hotter on I forget if its the inlet or outlet when the thing is fully warm. I got a laser thermometer at home despot for $20. That will have an effect on performance too. If you do the plenum I used Hughes and they give phone support and a link to great instructions. I also put in a new double timing chain, the TSB called for tensioner they never installed when they built them and a new water pump and everything I have mentioned along with whatever Hughes recommended I replace during the job. Edit- Oh yea I hit the CAT with a rubber hammer lightly and it had an improving effect which lead me to finding out about the point and shoot temp gauge method of determining if it was bad.

 

you dont have the top the dash apart to change the cluster bulbs. There's 6-10 t10 screws on the trim piece, then 4 t10 screws around the bezel, and thats it. Each gauge face is held in by Philips screws iirc, and once those are out, you can pull each gauge out individually. But you wont have to mess with the guages to see if theres a bulb in the check engine light spot.

 

That sounds more like the TV linkage not working right.

But yes, 4th IS OD.

Try reading the factory service manual; it covers all of that.

(There's one more point that you can feel a "shift" at; it's where the torque converter locks up. But that's not a gear.)

locking up torque converter makes sense, but its only 200 rpm higher than od at 50 LOL, I don't have access to a factory service manual, I'm having some trouble around here finding a Haynes manual for it cause I'm too stubborn to order one online


Now back to the TV cable, can I just disconnect it? I mean since my engine light doesn't work. I know that's a bulb since the truck starts.

 

No, you can't. TV cable modulates shift points according to throttle position. If you just disconnect it, the trans will believe that you aren't stepping on the gas, so, if it shifts at all, it will shift WAY early. Performance, and fuel economy will suffer.

 

Then you're too stubborn to use the proper tools. Here, take a rock and use it for a wrench. Sounds insulting? Then get over yourself. And the Haynes is NOT a Factory Service Manual; for somethings, it's worse than using a rock as a hammer! No, just hit Ebay and RockAuto and Bishko direct and order you a FSM. Otherwise, you're stumbling in the dark, too stubborn to turn on the light.

THIS.

The TV is Throttle Value; it's how the transmission knows how much throttle you're giving. Sounds like it's having problems if your transmission is shifting that early when you're into it.

Feel lucky; do that for a few miles in an AOD, and you've ended up with an expensive aluminum canister of clutch fragments and crud *grins* TV cable adjustment is critical on the Ford AOD; it's required, but won't kill the transmission as quickly, on the TorqueFlite transmissions.

Once again here is the proper procedure for setting the TV Cable at both ends. https://www.justanswer.com/dodge/1ot...-throttle.html
Here is a FSM for $40 http://www.ebay.com/itm/NICE-Mopar-D...ZY6tVN&vxp=mtr

You have to make an effort there is no easier softer way. People here take time to work out what they are offering you, show some gratitude by demonstrating understanding of that.

 

Thanks (again) now the big question is, what if the cable is broken off? is that a real bad thing? Will it still shift?
I'm an old car mechanic nothing electric

 

why are you not reading what people are telling you? A broken tv cable is going to be exactly like the answer Ralph told you if you wanted to take it off.

How about just ripping it all out, put a carbed 318 or 360 in it, and a 727 4x4 amd be done with it? At least then you should be able to understand something about it.

 

Well, would it be a real bad thing for transmission pressure to go too high or too low, to shift at the wrong place, and to burn the clutches off?

TV cables beat vacuum demods since you can't suck transmission fluid when the TV cable is off any ...

It'll shift, but it'll shift like the throttle is closed, not like you've got the throttle anywhere. Until the clutches burn out due to the shifting being way, WAY off.

And I have to ask - you never worked on a vehicle with a TV or kickdown cable or linkage? *boggles* Even my 1967 Mustang had a kickdown/TV linkage; how long has it BEEN since you've worked on a vehicle?
