    General Discussion
    Hi it's Rodney here from Wholesale Automatic Transmissions, Does anyone know if there is a Isuzu 4BD1 - GM 4L80E Adapter plate available? We are doing a manual to auto conversion for a customer into a Land Rover Defender that is already fitted with the Isuzu 4BD1. I have everything else but was...
  2. Chevy Transmission Selection

    Transmission, Adapter, Transfercase Discussion
    Hey All, I know there have been a lot of posts out there on the chevy transmissions...because I've read most of them. I'm still having a difficult time deciding which route to go for my rig. I have a 1964 C50 cab mounted on an 87 v10 frame and running gear. Has 350tbi / 700r4/ 208. Looking to...
  3. 6.5 Non-Turbo Diesels in P-30 Step vans

    Performance Discussion
    I picked up a couple P-30's with naturally asperated 6.5's. One has a 4L80E behind it and the other is missing the tranny. The mechanic that services them says that they both run. The one with the trasnsmission has a tapping like a wrist pin sound at the top of the stroke. It has been running...

    Isuzu 4BD1T/2T
    First, thank you to all who have purchased these kits and other conversion parts from supporting vendors of this site. The GM adapter kits are close in function to kits that were sold by IDS, but with some design differences. Our bellhousing adapters are CNC machined from 6061 plate. The...

    New to the forum, wanted to post my project on here as well as my plans for it in hopes for some feedback and pointers.

  6. 4L80e: Hard shift between 1-2

    Transmission, Adapter, Transfercase Discussion
    Just got my F150 project running last thursday the 8th. I'm running a '93 4L80e with an Optishift controller. Now when at light to mid throttle, the shifting between all the gears is nice and easy almost not even noticeable...but at full throttle, the 1-2 shift delays a bit then kicks like a...
  7. 4BT & 4L80E Setup Questions

    Transmission, Adapter, Transfercase Discussion
    Been digging around here for hours trying to find the answers to a few questions as I put together this 98 Suburban 2500 4x4. It will be used as a daily driver and see rare, light, towing. Planning to use the stock transmission and transfer cases. My questions at this point are: 1. Torque...
  8. 98 Suburban 2500 4x4 - 4BT - 4L80E

    Buildup Showcase Threads - All Engines, Vehicles
    Been wanting to tackle this sort of project for awhile and finally pulled the trigger. Picked up the suburban a week ago and my 4BT arrived late last night. This truck will be primarily for driving around town and very little light towing. I chose the suburban because the price was right and I...
  9. 4BD1T Into 1999 Suburban

    Buildup Showcase Threads - All Engines, Vehicles
    I've been lurking on this site for years, but finally decided to take the leap and go after a diesel conversion of my own. My ideal vehicle would be a 4-door pickup to haul my family, dogs, and any junk we want to take along, but I wasn't finding any great deals on those. I had an idea one day...
  10. 85 f150 4bt

    Buildup Showcase Threads - All Engines, Vehicles
    Started thinking about this build since April ‘10. Since then I've been gathering up most all the parts. The truck started out as an 1985 F-150 5.0 EFI 4x4 AOD/NP208 with 3.55 axle gearing (I believe, been a while since I've checked.) with 31" tires. Plan to make it an 1985 F-150 4BT 4x4...
