Park to Reverse

[Truck Co 202]

Had an interesting one the other day. It has only happened twice in the last few weeks.

Left work, drove 65 miles home (90% interstate), got home and idled the truck for 10-15 minutes while clearing snow on the driveway. I don't remember if it was on high idle or not. Got in and put the truck in reverse, nothing happened. Shifted back to park then back to reverse worked just fine. Similiar situation the otherday, and i put it in reverse nothing and as i tapped the gas it "bumped" into reverse.

I have 90K on a mostly highway miles 03, I do 30-35k a year. I am planning a fluid change shortly, stick is full and clean. Fluid was done at 60k which was less than a year ago.

What should I be considering as a possible culprit. I have not noticed any other issues.

I checked the trans fluid once more. Usually I check the trans cold & not running. This time I checked the fluid running and warm and it registered low, however the truck was parked uphill. I was planning to check the fluid again on a level surface. I have not had the problem in a few weeks. It has only happened twice that I remember. I stopped at a few parts stores and found out they do not have the MERCON SP fluid. So I figure I will pick up a qt next time I pass the dealer.

Ask Orielly's Auto Parts. If they don't have it, they can order it. It is about $3.xx a quart, instead of $8.xx like the dealer.

HUH??? There is no vehicle where that is the correct way.

My 04 does that from time to time. I really think it has to do with how quick you get on the throttle after you put it into reverse. I can make mine do it every time, so I just put it in reverse and give it at least a full second before giving any throttle.

I agree, it will not register within normal parameters, but it usually sits in the same spot each time. When you run the truck it then falls into line with the temp of the fluid. If you notice a difference in the off/cold mark that you remember, be sure to check it running.

I've learned that hard way that this "delay" situation is not normal whatso ever, it is the beginin of the end...if not taken care of early!! I had the same condition that I let go for about 6 months till a tech told me to have it fixed asap or else.......so I got fixed (replaced line pressure control solenoid, all filters,and flushed), worked awsome for about 500-600 miles then......I am now the proud owner of an all billet custom built trans, better priced than the mail order ones, just as well built if not better......

tranny fluid level is a pain...i hate it. kinda stupid they can't devise a system like the lube oil check....

I have not experienced the problem in almost a month.

What did you have done to fix the issue? Line Pressure Control Solenoid? So that did not fix the problem?
