all this talk about nv4500s reminds me that I need to open up the one in my 95. does anyone have a source for a good rebuild manual?
What would cause the stock bellhousing to not work? Chevy offered the 1995 Nv4500 with the small block engine on pickups, and the LQ4 bolt pattern is the same as the small block.Quicktime is the only known bellhousing that works with the early up to 1995 smalish bearing retainer to chevy engine bolt pattern I'm aware of.
Far as I'm aware it is.Ironic!
Just wondering - Is your output housing stock?
Shift forks looked fine, detents feel fine.I've put several 100k of miles on NV4500's using BG SynchroShift fluid. Its completely priced with the Mopar and GM stuff.
With that said, OP's noise is not a fluid issue. I'm deaf AF and it sounds to me like rattlin blocking rings and/or syncro sleeves. Seems to shift ok though.
How about the clutch fork rattling around?
What do the shift forks and detent look and feel like?
I would expect any issue with the clutch, bellhousing, pilot bearing, ect. to happen almost all the time. With no load on the transmission the only change in noise should be from an rpm increase or pushing the clutch in. I don't feel like anything in that area should cause an issue in only 4th and 5th. In the trans failure with the pilot bearing you mentioned, everything got lost except 4th, not just one or two gears.I've been doing alot of research on the nv4500/ls and alot of the aftermarket bellhousings aren't perfectly in line and cause issues. Also check your clutch. Might have lost a weight

Its the pattern on the trans side of the bellhousing not the engine side. The early GM nv4500ss had their own unquie bolt pattern on the trans side. In mid to late 95 they went to the same bolt pattern that dodge used.
