    Hello,
    I was told to contact you and see if you would take a look at my thread and possibly give some insight.
    Any help is very appreciated. Thank You in advanced. Power Strokes 1994-1997 General / clutch fan vs. straight fan.
    It did get off topic from the subject but certain ideas popped up that left more questions and areas to dwell on.

    Hello Mark, I just got a 2010 F250 6.4 D. 90K miles. I want to flush ALL the fluids and change filters. I got a quote from a local shop for 1600.00. Little high for my budget. needs power steering and tranny for sure. That plus oil lands me at $800.00. Is this a fair price? Anything you would recommend at this mileage for preventative maintenance?
    thank you sir,

    Hello Mark, Newbie here with an engine tranny swap question. Can I bolt a newer 2001 7.3 engine up to an OBS 1997 7.3 which has the E4OD tranny ? Or do I need the 2001 4R100 trany, T-case and complete truck wiring harness with it also? Thanks for your time and info.

    Hey Mark I have a quick question about the 7.3 4r100 with the ebrake on it. I know it has the same tailhousing as the 4x4 , but will it work in a 4x4 truck? It appears the VSS is located on the Ebrake. Thanks for your time.

    Mark, please let me know if you think after 15-20k miles on a new reman 4r100hd transmission in a 2001 f350 dually i should just change the fluid or also change the filter. just called our dealer and he said a new filter was not needed when i ask him to do both. i pull a 10,000 lb camper in the summer so i dont want any more transmission problems. Thank you for your time and advice,

    Battery was disconnected when the upgrades were made. Also cleared the memory again, by disconnecting the battery. It's still flaring. It seems 2-3 shift and 3-5 shift are flaring. Hoping it's just the solenoids (fingers crossed). Which solenoids would you recommend replacing/upgrading? EPC, Coast and Direct?

    Hey Mark, I'm new here at TheDieselStop. Looking for more information on an issue I'm having with my trucks transmission (5R110). What I know so far is that there is flaring 4-5 shifts, which I suspect is the solenoid but I also hear another sound coming from the transmission area. I just recently had APR headstuds, gaskets, IPR, glowplugs, EGR delete, and Oil cooler upgrade done. I'd hate to believe that it's the engine. It sounds like a rattling/vibarating sound through all gears including reverse and park. If I let the truck sit a while and turn it on, that sound is not present in till put it into drive or reverse and move a little it creates the sounds and persists to be there even in park. The sound and slight vibration remains in till I turn it the truck off and let it sit for a while. (note: sounds is there hot/warm or cold). Is there any information you can provide before I start this project?
