Mr. TOBASH; Respectfully, I must ask - are you an experienced diesel mechanic? I've been fooling with these things since 1969 and installing turbochargers on diesels since 1985. While I do not claim to be an expert, I have learned a great deal from my experiences over the years. I have owned...

Update on 700R4 in my M1028 - When I began assembling my new P400 6.5 drivetrain in 2018, I reached out to Chris Gardner at Bowtie Overdrives in Hesperia, California for his recommendation for a rebuilt 700R4. At the time, I had planned to keep the engine naturally aspirated, as the P400 is...

Hey Tobash - I thought you went with a 765R4?

Thanks !

Hey Sir - how did you adjust the TV cable? Did you adjust it at the bracket or did you install a gauge onto the transmission? Chris at Bowtie recommends using the gauge, however I believe an accurate adjustment can be made at the bracket.

I haven't progressed that far yet with Bullet. However their 6.5 unit is not something they "just came out with". They currently have many units running on 6.5's, so evidently they have addressed the matter. I will re-post here when I have answers.

Have you identified the exact Whipple unit you plan to install? I would ike to look at it and compare it to the Bullet. Thanks.

I have already measured things out for my M1028 CUCV truck. No problems there. The top of the blower is no higher than the top of the air cleaner. Regarding one of these in a HMMWV, I found an article on the subject which seems to indicate that it would fit with no problem -...

Ahem, my rebuilder IS Bowtie. Chris Gardner is, in my opinion, one of the most knowledgable in the business on transmissions. I purchased a Level 2 K-case from him a couple years ago and bolted it behind my new P400, which is still sitting on my engine stand awaiting to be installed into my...

Bowtie's 765R4 is the ultimate transmission, no doubt. It has a base price of $3700. Their Level 3 700R4 is almost as strong at $1950 and should provide ample strength for a HMMWV 6.5. Just saying.

Just thought I would add to this thread a bit. After having and recovering from another heart attack last August, I managed to get my NP241c mounted on the back of my Bowtie 700R4 in February. Everything worked as it should with no issues, except a leaky front output shaft on the 241. This...

Guys, please excuse me for being so dumb, but what is wrong with sourcing a Level 2 K-case 700R4 from Bowtie Overdrives for $1650.00? This unit is rated to handle 450 HP and 450 FPT. It is the exact unit that I have bolted behind my P400 engine going into my M1028...

I purchased a Level 2 K-case 700R4 with special output shaft from Bowtie for just under $2500 including crating and freight from California to Kentucky. Is this more than you want to spend?

Joe - the single most important thing about the 700R4 is correct adjustment of the TV cable. You set this adjustment at the TV bracket with WOT. Also, make sure your accelerator pedal is opening the injector pump to WOT when the pedal is fully depressed. Looking forward to the photos.

C'mon man. If built correctly, the 700R4 will handle as much as a TH400. I purchased a Level 2 K-case 700R4 from Bowtie Overdrives rated at 450 HP and 400 FPT. $1650.00. Added the special output shaft to mate with my NP208. The length of the 700R4 is the same as the TH400 so no crossmember...

Probably more than most folks will want to spend. For me however, cost is not important because I am spending my daughter's inheritance. After having multiple surgeries and a heart attack which almost got me, my goal in life is now to expend all my wealth to fund the items on my bucket list...

Since my 700R4 is going into a M1028 truck, your specific circumstances to install it into a HMMWV may and probably will be different. Having said that, the GM part number for the adapter between the 700R4 and NP208 is 14038663, which is taller than the OEM adapter used behind the TH400. Not...

I own a M1028 truck which has the TH400 3-speed transmission and 4.56 gears. Top speed around 50 mph, downright scary on the interstate, engine sounding like a Japanese motorcycle. A few months ago I made the decision to change-out the TH400 with a 4-speed transmission to pick-up a little extra...
