Posted February 19, 201015 yr What were the problems years that dodge had with the nv4500 transmission?
February 19, 201015 yr Owner Ummmm... The only thing I knew of was the 5th gear nut problem... But as for myself with a 2002 I've got 162K on the clock and still going without a transmission problem.
February 19, 201015 yr My old '99 with the NV4500, has over 170,000 on her. No issues at all. I gave my '99 to the parents, when I got my 04.5 in June of '04. It had 143,000 miles on it then..............In 5+ years, the P's have only put less than 25,000 miles on her!!!!!:neutral: Still has the original clutch, VP, lift pump etc..........:lol: When I had that truck, I drove the piss out of it!!!!! It's leading a charmed life now. Although, I'll probably get it back in the near future............the P's are getting old and Dad doesn't like the manual tranny so much anymore!!!:cool:
February 20, 201015 yr from what i understand...the main shaft is the real culprit. in fact that is often the permanent fix. i have read that 99s and newer have a "revised" 5th gear nut...but it can still have this problem
February 20, 201015 yr i found this info if your curious....http://quad4x4.com/Dodge%2094-04%20NV4500.htm
February 23, 201015 yr Just like most manual transmissions the previous owner or a mechanic dumping the wrong fluid in can cause problems. IIRC the NV4500 uses a gear lube of 75W90 but it MUST be GL-4 rated to prevent the lube from attacking the yellow metals in the transmission.
February 23, 201015 yr Owner As for myself I've been using the Mopar Brand trans fluid but this go around I might look towards another brand that might work in place of... $23 to $27 a quart for Mopar's Trans Fluid and you need a 1 gallon (4 quarts) it sure does hurt...

IIRC the NV4500 uses a gear lube of 75W90 but it MUST be GL-4 rated to prevent the lube from attacking the yellow metals in the transmission. :iagree:but gl4 is a rating that is rarely used today(i think someone said its a really old military spec). you will usually find GL5/MT1. most people will tell you that GL5 is compatible with GL4...but when you look at the criteria for rating, GL5/MT1 has more of the stuff that harms the yellow metals. i read up on this back when i had a trans flush and fill. because not all oils are the same...i do think that SOME GL5/MT1's will work...but i didn't want to the test bed at that time.
