No Response On Gas Pedal Suspected Transmission Issue
Hello all,
I’ve got a 1986 C4 and was on a night drive the other day. Know a nice straight piece of road I often go to and get the car up to speed every now and then. The last time I did it however I ran into a major issue, when the car tried to switch from 3rd into 4th gear I lost all gas pedal response, as the title stated I suspect it is a transmission issue. I think it’s important to highlight that I had the gas pedal all the way down which might not have given the transmission time to reconnect properly. I’m not sure, when I reduced speed and brought it down to the first gear range it would just stay there. Any suggestions as to what it might be are appreciated also if I did not give enough info about the event please say so since it’s my first time posting. Thanks in advance.
Edit 1: It’s a 4 speed automatic transmission.

The trans fluid should not be a problem I believe I checked it a month ago and it was at the appropriate level with good coloring. The throttle cable also looks fine to me I can see it pulling back when I press the gas pedal.

Ok the problem seems to have sorted itself out. Was doing some other work on it where I had to disconnect the battery. Out of curiosity I fired it up and tried to put it in reverse to see if it would work and to my surprise it did. Took it out for a bit and it changed gears fine. I suspect that the ECU needed a hard reset or something since that’s the only thing that I can think of that would make a difference.

Sounds like it's time to pull the trans. That's what I'd do, but a trans expert would be able to give better advice that I can. I think @arbee know the 700R4 well...
