Hi this is Mike Reimann from Dallas. I had forgotten I was a member of this forum since 2006 I noticed recent comments on this forum about my hand built car, MDR GT. A photographer from Germany, Rainer Selzer, posted a story about my project. Use either of the following web addresses to read...

I agree with Mike Drew. However, this one was not for a GT40. I have documentation from ZF that gives production numbers for the -0s, -1s and early -2s. Only 252 units designated -0 were produced for the Ford GT40. (See attached PDF) This input shaft on the pictured trans is longer than...

Per Dave's request I'm attaching photos and design notes for my shifter and linkage. For anyone interested you will also find a brief description of my one-off handbuild car - work in progress. Dr. Mike

Is anyone is still trying to solve these two problems? 1 - Shift linkage for ZF5DS25-0 or ZF5DS25-1 transaxles. 2 - Throttle creep in a CNC model 290 hydraulic throttle. I have experimented with all the alternatives discussed in this thread except implementation of a cable shifter. My...

Johan, The information I previously posted about the ZF shift pattern comes from the ZF 5DS25-2 service manual. This is the specification for the shifter mechanism on the transaxle. The shifter positions at the driver's end will probably differ slightly from the gearbox due to variations in...

Wayne, For the ZF 5DS25-0, -1 and -2 the shift pattern is Neutral - Center Reverse - Left forward First - Left back Second - Center forward Third - Center back Forth - Right forward Fifth - Right back The positions, displacements and rotations of the shift linkage is shown in the...

Hi ya'll, Maybe I can provide a little history. The original Ford GT40's production race cars primarily used one of two gearboxes. The GT40's were powered by 289 cid engine and used a Colotti 4 speed transaxle. Colotti's were the only viable and available gearbox in the early production...

Bune, The Pantera gearbox is a ZF 5DS25-2. Ford GT40 MK3s were the "Street" version of the GT40s and the only ones that used ZF boxes. These transaxles were used in ther MK3s because the are sychromesh (use hylically cut gears) and cannot handle the power demands of LeMans racing. I believe...
