5 speed tranny suggestions

Postby jmd4993 » Mon Dec 09, 2013 10:11 pm

so i did a getrag swap about 3 weeks ago. I installed a valair dual disc clutch. i finally got to start driving the truck at the beginning of this week. When i shift to 3rd gear it grinds and won't let me shift until the rpms are way down.

Ive heard a few things. that its a weak slave cylinder and i need a heavy duty one. that its a top cover issue which hasnt been explained to me yet. or its a syncro which i hope its not. so here are my options.

before i tell you that. im building this truck to be bullet proof, strong, and can tow and haul alot. dont care about speed.

1. so the guy that sold me the tranny said that he has another tranny he can trade me but he doesn't know that history but the previous owner said it was fine. the engine in that truck was blown so he couldn't test it. so i can put that one in and see if that works.

2.im gonna order a valair heavy duty master and slave cylinder to see if that helps. plus i heard its must have with these heavy duty clutches.

3. a guy in New Hampshire said he'd sell me a NV4500 rebuilt with no core return needed for $1450. then i could sell my getrag which idk what you can get for them with a bad syncro. its only got 124k miles on it. but is there alot id have to do to accompany an nv4500. my trucks a 4x4 and i have the np205 tcase too. ive heard you can just flip them over to fit on the nv4500 but what do you do about the front drive shaft?

4. Or if you think the getrag is better for towing and everything. If that other tranny isnt good then a diesel shop said they'd rebuilding it out of the truck for $1000 or have to take out the tranny themselves for $1500.

what do you think i should do? what would be the best cost to benefit ratio?

any info is greatly appreciated thanks a lot.

Stay with the getrag....there's more to swaping in a 4500 than just bolting it in. I'll be replying on your other tread about the top cover issue.

X2 on the Getrag. NV swaps aren't all hard, it's just all the little stuff that comes with it, i.e, transfer case shifter bracket, transmission mount, etc. The NP205 bolts up just the same as it would behind a Getrag. Getrag's are good transmissions in my honest opinion ;)

im gonna rebuild the getrag instead of trying that other getrag the guy has cause from the sound of it, its probably not a good tranny.

does anyone know of a good place in new england that rebuilds getrags at a good price

PDS diesel is palmer, Ma quoted me at $1000 with me taking the tranny out and $1500 for them to take it out.

A grand is kinda steep,imho. I'd find a trans shop somewhere that's not a diesel go fast place. More than likely you'll end up with the same job.

Before I knew better (and learned), I was working on my brothers 02, it cost us $550 for a trans shop to go through his NV4500. Had the common third gear scratch, so it got new synchros and bearings. I pulled the trans and brought it too them. Now that I've built an NV, its really simple and could have saved more money. There is a great write up in here on Getrags, could save ya some $$$ by going through it yourself ;)

i would love to do that for the learning experience but im living at home right now and only have a two car garage and limited space.

im just gonna get a fully rebuilt one off ebay with 0 miles and itll be the same maybe a little less that having a shop rebuild it. then i know its good to go for a long time. and they have a 12-36 month warranty

You don't need that much room, I rebuilt my truck in my driveway...the garage is too small even though its classified as a two car...literally fits to small cars.

There's also a PDF of the Getrag service manual floating around. Always good to download and read through, even if you're not going to rebuild it yourself.
