NHTSA Complaint #10054616 — 2001 FORD RANGER

I HAVE A 01 RANGER 4X4 WITH 4.0L ENGINE AND 4.10 REAR END. I CONTINUE TO HAVE AN INTERMITANT SHUDDER PROBLEM FROM 1-2 AND THEN AGAIN FROM 3-4 (AROUND 2500 RPMS) AND 4-5 (AROUND 2100 RPMS). I HAVE HAD THE TRANSMISSION SERVICED SEVERAL TIMES AND HAD THE FOLLOWING REPAIRS PERFORMED: 1. REPLACED DRIVESHAFT 2. OVERHAUL VALVE BODY 3. PCM REPROGRAMMED 4. REPLACED VALVE BODY 5. REPLACED VALVE BODY AGAIN 6. OVERHAULED TRANSMISSION REPLACE OVERDRIVE DRUM DUE TO AN UNEVEN SURFACE SO FAR, I HAVE HAD OVER $2,500 IN REPAIRS (ALL UNDER WARRANTY LUCKILY). HOWEVER, THE SHUDDER IS STILL THERE, ALTHOUGH IT IS NOT AS HARSH AS IT ONCE WAS. A NEW PROBLEM HAS BEGUN IN THE LAST FEW WEEKS, NOW WHEN YOU PUT IT IN GEAR, IT TAKES SEVERAL SECONDS BEFORE IT ENGAGES. IN FACT, YOU CAN SIT THERE WITH YOUR FOOT ON THE GAS AND IT WON'T GO. ONCE THE TRUCK IS WARMED UP, THIS IS NOT A PROBLEM. THE SHUDDER THAT IS FELT IS ERRATIC, BUT CAN BE MADE TO SHUDDER IF DRIVEN AT THE CORRECT SPEEDS. *AK
