A couple models of Clark, direct and OD, and a NP542 possibly.
What year?
Post the VIN and all the codes off the info plate for better answers.
As long as it shifts, and doesn't pop out of gear, whine and growl when it shouldn't, it's as good as any.

5 speeds
I suppose this would relate to the year or years of the trucks. Mostly
in the fiftys all atleast I know of were Clarks 5 spd. 4spds mainly
Warners then getting in the sixtys they used a lot of Spicers med and
HD. then N Process. My guide has been Clarks 1st & reverse being to
the right with rev up to the glove comp. Spicer 1st to the left with rev
up to the instrument panel. Im pretty sure of this cause I have all
four of these 5sp trannys. I have not had any issues with either one.

Thanks - I know it would help if I had the VIN stuff but it's in a truck I'm going to look at and that's had the tran replaced. Now, the new tran is still acting up (hard to shift between certain gears ....), so I just wanted to check if there was a trans to AVOID. BTW - this is a 5+2 in a 1991 F600 6.6L rig I've mentioned in a previous thread.
Thanks again.

Sorry, didn't recognize the name--seller is getting that fixed, right? Difficulty in shifting could be synchros or could be a clutch issue.
AFAIK, IIRC, never seen any comments here about 5 speeds to avoid by model etc, just some common problems with the NV4500 in Dodges, and the usual "worn out" condition of high-mile units.
