Bucking in 5th gear only...

HISSIN50 said:

what revs are you turning in 5th when this occurs?
i would surmise you are at low revs (if you have stock gears) and there is a tiny bit of surging, etc which is exacerbated from the low revs, lack of torque and throttle input.

my two cents - more info would help. good luck.

More info would help, but I would start by checking your ignition components. Old plugs & wires can cause symptoms like you're describing.

How's reverse?

Your gonna need to drop the tranny to be sure. Probably a worn synchro or bent 5th/reverse shaft.

I recommend you buy a Tremec.
