Default Shift question

I had to redo the heads on my 95 because of a burnt exhaust valve. I bought the car "as is" that way - real cheap.

Since I had the heads redone (new valves, springs etc) and added scorpion 1.6 rooler rockers the engine revs quickly to the shiftpoint at full throttle. Since I have no previous experience with this car when it was running correctly I don't know what the before and after difference is.

The engine is still pulling strong when the automatic trans shifts at full throttle and I was wondering if I should reprogram the shift point of the trans ?

I had read from this site that it is not good to shift manually.

Thanks,

Bob

You can buy a B&M kit from Summit to conveniently change the springs & weights in your 700R/4 governor body so as to modify the WOT shift points.

In some cases manually shifting can cause more stress & wear but not in the case that interests you. After all it matters not if you manually hold the WOT shift point or reprogram the governor.

I thought that the shift points were controller by the pcm.

My trans is a 4L60E.

Are you saying that a manual 1 - 2 upshift is not necessarly bad for the trans ? Just upshift when I feel no more pull from the engine ? The tach seens very hard to read in the upper range and I question its accuracy.
