Transmission question
Is there a 5 speed transmission for the F-150 that has the bulldog 1st gear AND overdrive also?
Can it be interchanged with a 4 speed?
Does it require a driveshaft change also?
My truck is currently equipped with a 4 speed that has the bulldog 1st gear, and if they are available, I would like to get a 5 speed to replace my existing transmission. I DO NOT want to give up the granny gear though>>>>>>>>>
Has anyone done this? And was it a worth while upgrade?
Thanks in advance for the replies..........

Richmond used to offer a 5 speed that had a 4.41 first gear, but it still has a 1:1 fifth. All that would accomplish is adding a gear in the middle and moving them all closer together. I don't know if the shifter on this trans will work in the trucks. There is also a Richmond 6 speed that has a 3.27 1st and a .76 6th. Of course, neither of these will do you any good over what you've got. Your best bet is probably to get a M5OD and install 3.73 gears. This should get you an overall ratio just a little bit numerically lower than what you've got, plus lower your rpm at 60 mph by around 5%. One of these days I'm going to put a T56 in my truck so I can enjoy the low end of some 4.10's while cruising the highway like I have 2.05's. All it takes is money....

Transmission question
The ZF used in the late model 250s and 350s will bolt up to your engine. It has a granny 1st and an OD 5th. You'll need to do something about the hydraulic clutch it requires and fab up a chassis mount and shorten the driveshaft.
Alternatively, Advanced Adaptors makes a kit to install a NV4500 5-speed from a late model Dodge 250/350 in a Ford. It's also a Granny 1st OD 5th box. It is a bit more expensive tranny, but the kit fits it to your existing bellhousing so you won't have to mess with the clutch.

The ZF S5-42 is about as expensive a transmission as any, ranging from $800-1300 used and even more rebuilt. But it is the only Ford OE manual with a granny 1st and OD. The M5OD's 1st isn't nearly as deep, and it's strictly a light-duty transmission.

Transmission question
Steve, try about $900 used, or $1200 rebuilt. These trannys are awesome, but do require a little driveshaft modification. You may also need to modify the t-case shifter, or use one specifically for the ZF. I am hoping to put one behind the 300-6TT I am building. They are pretty close gear ranges, first is something like 5.7:1, versus the ~6.8:1 in the NP-435. Still decently low, and synchro'ed too! This, for me, is a best of both worlds transmission.

Transmission question
Thanks everyone, I'll think I'll look for a NP-435...
I do not want to spend $1200.00 or more for a tranny...
I was hoping I could get one in the $300.00-$500.00 price range.....
Will the NP-435 bolt to my bellhousing?? Can I use my existing driveshaft or do I need to get one from the truck I get the tranny from??

ftwfred-
You may already have the NP435 if you have the granny low 1st in a 4 spd. If it isn't the NP then you may have the BW T18. It is a lot cheaper to get another NP435 than to get any 5 speed that will just drop in.
