slow to enguage into drive or reverse

[motoxraca33]

so a month ago the fuel pump went on my truck so it sat in the driveway for about 3 weeks not moving. my driveway is kind of steep and the front end was up hill...not sure if that has anything to do with it, but ever since then its been going into gear really slow and sometimes slipps for a second then kind of like jams into gear. it doesnt slip once its in gear... drives normal, just takes about 2-3 seconds to enguage. its scaring the crap out of me!!!!! i really appriciate the help!!

The reverse in my truck has been doing this on and off for a while. I haven't been too worried about it, but will be interested to hear what others have to say.

Battery disconnect, Dead battery

ANY TIME the battery is disconnected for ANY reason, a new PCM has been installed, or the calibration has been reflashed, the adaptive strategy for the "Engagement Schedule" MUST be updated.
1. Install diagnostic equipment and monitor TFT.
2. Warm the transmission fluid to 130F degrees as indicated by the TFT.
3. Perform 5 engagements from PARK TO REVERSE
Each engagement must be five seconds apart.
4. Perform 5 engagements from DRIVE TO REVERSE
Each engagement must be five seconds apart.
5. Perform 5 engagements from REVERSE TO DRIVE
Each engagement must be five seconds apart.
6. Perform 5 engagements from NEUTRAL TO DRIVE
Each engagement must be five seconds apart.

^^^^ That is what I was just about to post. Even when I don't have an issue after a battery disconnect this makes things faster.

Its part of the relearn procedure for the tranny, I'll post the document if I can find it.

My RAZR made me send this...

I have it on my phone but it won't let me upload it, I'll put it up as soon as I'm home

The 5r110w (torqshift) learns how to shift as the clutch packs wear. This allows for firm shifts as the trans wears. When you disconnect t the battery the trans has to relearn this. This procedure helps the trans relearn where it needs to be at.

[squirelly87]

The procedure I wrote is directly out of the 5r110w rebuild manual.

I honestly am not meaning a hijack here, but I think this is somewhat related. Does the tranny go thru an adaptive learning process right after a tune is loaded? Every time I have loaded my SRL, it has shifted firm on all shifts, then after awhile, usually a week or so of driving, ALL of the shifts get softer, by quite a bit. Then if I return to stock, or load the tow tune, then go back to SRL, same thing, every time.
