??Transmission?? I don't know

[Snoopsters]

I am a proud owner of a 93 ATX Green (Deep Jewel? more like rough) SHO. I have taken the car to the transmission shop twice and paid dearly for it. These are the symptoms and what I have done sooooo far...
I pulled the codes about a month ago, the VSS was weak or no signal. When I went down to the Zone to get a new one the harmonic balancer fell apart and shut the car down. Got that fixed. The codes were run again after the balancer was fixed, the VSS had no code and was fine. The car has been acting sluggish when I mashed down on the accelerator (flooring it). The engine wants to run but the rest of the car doesn't. I ran codes. The VSS acted up again. Replaced that. But, I am having the same problem. SYMPTOMS: When I climb hills, the car will not go over the 3200rpm mark in 4th gear. There is wrong shifting at different times during normal driving, however, when I ease on the gas, the shifting is fine. ONLY when I floor it. I have had it to the tranny shop and they tore it down to look at it and said " they can see anything wrong". I took it to Mr. Transmission and they said the same thing. But they said it felt like a clogged exhaust. So I had the cats cutoff and the exhaust overhauled. Still the problem exists. I checked codes again, no error codes. I took it to FORD...$95 later... THEY don't know. They suggested that they should overhaul the car for $705 to find out what the problem is... ANY SUGGESTIONS? eek! oh_my oh_my oh_my shrug

I don't have alot of experience with these trannys. The '93 ATX is the weakest of the SHO auto trannys.

IF it is a transmission problem, spend the money once and get the job done right. Take it to Doug Lewis at Ford Specialists of Georgia. The most reliable, verifiable, end up with a better setup, transmission work out there. It will cost you up front, but you won't have to take it back again and again like many owners have had to do.

But the transmission shops said that there is nothing wrong with the transmission. Could it be the TPS?

it doesnt *sound* like the TPS, but thats an item which is easy enough to pull off and test with a voltmeter, so you should check it out anyway.

SNOOP,

You need to understand that the computer stores a code when it does not get the signal from a sensor that it is expecting (whatever it is programmed to expect).

The signal can be in volts, milivolts, and ohms resistance. The signal gets to the computer via wires and through connections. The signal can be a continuous voltage, a range of volts, a pulse, ohms resistance or a varying range of ohms resistance.

Anything the interferes with the signal, such as a corroded connection, a loose connection, a shorted or open wire, or a failing sensor, will trigger a code.

The point is that a code does not automatically mean that the sensor has failed. So, before jumping to the conclusion that the sensor is bad, check the circuitry and the connections.

One part of the circuitry that can cause numerous problems are the "grounds". Make sure all of your grounds have good clean connections.

After you have checked you circuitry and your grounds, clear the codes, drive it , and see if the code comes back. Hope this helps, rangerj
