My 96 automatic XJ has 189xxx miles. Slowly, through the last 10,000 miles, my overdrive gear shiftpoint has become lower and lower in rpm, now to the point where it completely bogs the engine down to 1000-1200rpms. What or why is this happening, and can it be fixed? The only notable problem with my transmission is that it needs a new torque converter, and that is only noticeable under hard acceleration.
Let me know what you think, thanks.

 

TPS is a major player in that function

 

I actually replaced it a bit ago due to a wheeling incident.. I did not have the boging issue before or after the replacement..

 

What kind of wheeling incident damages a TPS?

 

Water. It fried from splashing too much in a puddle that was a bit deep

 

Gotcha. Not enough coffee yet this morning.
Ever done my Tip 10?

I have not, but it looks interesting

 

5 minute job.

Good signals can't travel well through crappy connections.

 

I have almost all those symptoms. Is there a easy/quick fix or no. Would replacing the torque converter fix it?
I've decided not to replace mine because I'm planning on an ax-15 swap...
So dropping the money on a new converter would be a waste on my end.

 

You should also adjust your TV cable on the throttle body.

 

I agree with that. I'll look into this weekend

 

I believe I've tried that before and had no noticeable differences
