I have a 1997 Dodge Ram 1500 4x4 with the 46RE tranny in it. My problem is when I reach about 30-35 mph it starts to shake but if I lay on the gas, it surpasses it and stops but will do it everytime I stop and go again. But if I turn the O/D off, it won't do it at all but then I can't surpass 55MPH and even that is pushing it because it stays at 2500rpms the whole time. What could be my problem? I was told OD Solenoid. But I want more opinions. Thanks!

 

Sounds like a misfire issue

 

Misfire like sparkplugs.?

 

Yep. When is the last time the truck had a tune up?

 

I just got the truck, so I am not too sure. Will go take a look now.

 

Sparkplugs look relatively new, same with wires.

 

What brand/type of plugs?

 

Champion Copper

 

Ok, those should be fine. Might not hurt to pull one or two, and see what they look like.

Distributor cap would be my next stop. Yep, it's a bear to get to......

 

We looked at all of them, they are good & distributor cap is good also.
