well after removing the tranny we found the culprint. the front bearing housing was loose. there was no protection from keeping the bolts tight. no lock washers , locktite etc.... the bearing inside is bad. so time for a complete overhaul. I also found out the previous owner replaced the clutch assembly including the pilot bearing and resurfaced the flywheel. :D

Thanks for all :help: it has been greatly appreciated! :fr:

after disassembling the tranny, the rest of the bearings all look new, however there is some nasty uneven looking wear on the 2nd gear. probably have to replace it along with n the main shaft as that bearing on front tore the heck out of it. might just have to find another tranny.
:2cents:
any ideas? :?

Talk about luck , we found a rebuilt NP for $50.00 that came out of a wrecked 1970 3/4 ton. they Guy was just parting the truck out most of it was gone , except for the tranny and misc body parts. :thup: he has all the receipts for the truck including the rebuild of the tranny . the tranny is still under warranty to boot!! :woohoo:
the truck is a mess, he did not do much to the body , but rebuilt the drive gearing and the 429 cobra jet. he had it blueprinted and balanced. lot of $$ put into that motor to make it turn 3000 rpm and drag out 367 horsies. The np was built for performance, he wanted to use it for hauling his trailers around. don't worry he also had the clutch assembly that went with it. Kevlar clutch. I might be buying the complete performance disc brake system from him , If I can scrape up the 150.00 . and no one else gets it.

ok now I am having an issue with this new transmission , and the company that says it is under warranty is not their fault for the following issue. the transmission 3rd gear is now very close to reverse and sometimes it is hard to find at higher rpm's like 1200-1500 . it was never like this before. sometimes while shifting it will try to go into reverse . that is how close these 2 gears are on the shifting pattern. there is hardly any play. it feel like it did as far as play goes when I first got it. It is like something moved. all the gears work great , no problems even 3rd once you can get it to engage without trying for reverse. Thought it might might be the syncros but then again I do not think so once you find it and it engages ever so nicely. :hmm:

That's classic T-18 after 40 years of abuse.

It's wear in the top plate, Put your old top plate on if it was lucky enough not to do it, or just grow to love it. I had a T-18 like that in a 70 F-100. I forgot it even did that at all after driving for 30K miles in a year. Got hurt and had a friend drive it with me riding passenger and they had to go through the learning curve again.

Personally, I think NP435's are the most enjoyable truck transmission to shift. If I had a problem with a T18 or T19 I'd toss it and swap in a 435. The NP's have a goofy synchro design that gives them their own unique shift feel. From an engineering perspective, by design, the NP's WILL go into ANY gear faster than a T-18 if you have the arm strength to rip it in whereas the BW's will not. The NP's just have a pretty cool old school synchro design that worked really good, must have cost a fortune to make compared to the other's stuff though.

that is what I thought it could be is the top plate. I also found out the warranty on the tranny is not as good as I thought it was. The company only guarantees their work on the shafts, gears , bearings , bushings and seals . nothing else. If they find any evidence of abuse, such as accidentally trying to go into reverse while going into third it will void the warranty. I also found out that the company does not use very good quality parts. I guess you get what you pay for, However it is A LOT better than my other tranny. Thank you for the help. I think I might look around for another top cover or see if I can fix this one. Oh and the guy I bought it from its highly upset with the company. he feels like he got ripped of from the company that rebuilt it. can you imagine with that much horse power and/or pulling a trailer what else could go wrong?

FINALLY!!! after much fighting and reporting with the tranny shop and writing a bad review to consumer affairs, I got another tranny. this time it was built buy another company that gives it a fully unlimited mileage warranty. they even will pay for the r/r of the tranny and shipping to and from the shop. The previous company I had been dealing with, outsourced this tranny order and It was shipped directly from this other company. I had looked at the reviews from this company and they were great, so it goes to show ya patients and perseverance pays off, most of the time
