Hi all, Odd problem developed today. 05 4x4 diesel, 145800k, Snowed today with ice under it. I used 4 wheel drive for 11 miles on snow which was unusual. At last turn before stop, I slid through intersection. Could hear and feel antilock system working. After stopping engine I heard antilock pump running for a few seconds. Never heard before. On restart transmission is odd. At first I thought I had shoved it into 4WD Low when I took it out of 4H. Not true it was in 2H It used to shift at 18mph now it goes up to 23mph. It tags the gear pretty stiffly as engine rpm is nearly 2000. Then I noticed it has a code light showing. Don't know what it is yet? Anyone had this symptom? Transmission seems normal for all other functions. Not sure if antilock involved, just was at same time. Any thoughts appreciated

My 05 did the same thing a few weeks ago- check for codes P-1751 & P-1754 mine was the TTVA - transmission throttle valve actuator 140.00 dollar part, 5 minute installation

Thanks, I was suspecting that possibility, from what I have read. Do happen to have part number?

mopar # is 53041140AB cost me $134.00 maybe you can find it cheaper when you install it you have to allow it time to reset itself [turn key on] or you will not be able to clear the mil light

Thanks again, I'll get one tomorrow, I have discovered a very detailed post about this same problem. It describes the key on no start procedure, after replacement. It was titled trouble code 1755. I'll post my results for benefits of others too. Sure helps to hear: "Been there done that, was not so bad" .

Same codes: 1751 and 1754, The ttva fixed my 05. The abs pump was not making noise it was the TTVA motor going thru some gyrations. When I turned the truck off it would shuttle back and forth ,off and on, or just make wierd noise. It was an easy install, hardest part was releasing the plug. Cost was $169.00. Could not argue was only 1 in stock at several dealer search. Tks again,05 doolie
