G56 Transmission - 273D Transfer Case - Rebuild

[CVR222NV]

I took the recommendation many o the Forum made and pulled my G56 transmission and New Process Gear 273D transfer case and shipped them to Standard Transmission & Gear in Ft Worth, Texas for rebuild. Transmission arrived late Friday (10/8) and by end of day Monday (10/11) they had the transmission and transfer case disassembled and inspected. Spoke to Joaquin and he stated the transmission and transfer case were in excellent overall condition and wondered why I sent them in??? I explained that I had my engine remanufactured and wanted to make sure the transmission and transfer case were rebuilt at the same time. Peace of mind mostly. I did explain that I was experiencing hard shifting in 2nd gear when starting out. I decided to post what Standard Transmission was recommending because it is different that DBM's NV5600 rebuild thread.

G56 Transmission

• Bearing and seal kit (recommended after any tear down)
• Synchros (mine were still 70-80% and Standard did not believe it was necessary to replace but I requested they go ahead and replace)
• Upgrade front bearing retainer from aluminum/pot metal to cast steel
• Upgrade reverse forks (early G56 transmissions only had spot welds on the reverse forks and is a known point of failure so Standard recommends welding the entire fork for additional strength)
• Remove passenger side Fast Cooler because it is too close to exhaust which defeats its purpose
• Oil - Amsoil Synchromesh - 8 quarts over fill with one Fast Cooler

New Process Gear 273D Transfer Case

• Chain and seal kit (chain was stretched so replace)
• Bearing kit (bearings were fine but I requested that they go ahead and replace)
• Oil - Amsoil Synthetic ATF

Cost

$2882.22 + shipping

Warranty

12,000 miles or 12 months

Any comments or thoughts would be greatly appreciated. Huge shout out for Standard Transmission & Gear. Excellent customer service!

That seems very reasonable.

Maybe keep the cooler and header wrap exhaust in the area.

Do you have the Fast cooler filter kit?

I do not have the Fast filter kit. I have not seen much discussion on the filter kit. I wondered if it was effective given that it only filtered oil indirectly splashing into the cooler.

Very!!! Blumenthal's pricing was $5695 for the transmission and $1895 for the transfer case.

I ran the Eaton string filter on mine until Fast came out with their filter. Magnets and the filter do some good. The filters came out looking dirty when I would change the trans oil. The syncro wear has to go somewhere. The design looks to be splash then gravity drain back through filter. Little discussion of filters extending oil life here:

Good information. My coolers were using the original PTO covers so I was going to replace them with the new covers to see if I can stop the leaking I have been experiencing. I think I'll get the cover with the sight glass and the filter kit.

BTW, South Bend Clutch appears to be using the heavy duty pilot bearing and I replaced that as well.
