a dumb question : are the recommended "shift points" in the 4sp same as toy's 5sp or in other words are the gear ratios equivalent in the 4 sp compared with the first 4 gears of the 5 sp?:doh:

I shift based upon engine rpm, not vehicle speed, therefore the shift points are the same regardless of the transmission...

thanks 2mbb for responding. to clarify: the reason why i am asking the dumb question is i am trying to determine why my new 5sp with less than 5,000 miles driven has developed at random times while driving in different gears, a disturbing loud whining?/hi pitched howling? noise to which i quickly either down/up shift to another gear to stop the noise. i was hoping that it is due to my improper shifting @ 1500-2000rpm (i shifted around 1500-2000 rpm in my original 4sp) rather than admitting i might have a defective/out of adjustment tranny?! i naturally got fixated on my speedo numbers when the sounds occur and it seems to be before/near the top end of recommended speeds before shifting to the next higher gear as recommended by toy's owner's manual. all the gears have definitely been "broken" in/loosened up compared to when it was the 5sp was first installed and driven.

thanks to input from all; your comments are appreciated. looks like i'm going to have to bite the bullet and take my truck in for inspection/repair! like they say, any strange sound/noise is not normal and serves as a warning that something is not right!

In your area take it to Mudrak's Custom Cruisers or orangefj45 here on Mud. None better and you are lucky to have them so close.
