O/D Flashing, loss of forward gear after engine install

[shane10]

Hi all, just finished up re-installing the engine after timing component work. First time pulling an engine so was a bit nervous to turn the key, fired her up and everything sounded great. HOWEVER, the OD light is flashing extremely rapidly, I'm talking 5+ times a second. There is also an apparently corresponding sound to the flashing light, a very rapid clicking/tapping. It's not very loud, could be engine related but sounds like it's coming more from the rear (possibly bell housing). Did I mess the trans pump up or something?
A bit weary to take it for a spin until I can figure out what's going on, any input appreciated

On a side note, I let it idle for close to 10 minutes, the temp gauge was right where it should be, but the upper radiator hose was still dead cold, will this just take some extra minutes for the thermostat to open and let things flow?
Thanks

Went for a test drive, have reverse but almost no forward gear, I had to rev up to about 3k RPM to slowly creep back up the driveway. I dropped the pan and replaced the filter/fluid before driving, fluid level is good, with engine running it had no problem sucking the trans fluid up through the fill hole, pump is good? Guessing I messed the TQ up someway/somehow.
Any inclinations as to what the issue may be?

Will probably end up having the trans rebuilt or buy a reman and have a mechanic friend install as not mess anything else up. 100k and 6 years on the last rebuild, I got my moneys worth (I guess)...
As far as that goes, I know it's a common topic, but reman or rebuild? Any reputable reman companies highly suggested?
Thanks

If the only issues you had prior to the engine pull was the timing chain slides I certainly would assume that any other issues including the tapping noise that you have after re-assembly is caused by something not put back together correctly. It the transmission worked fine before, I see no other issues unless the fluid level is not correct which is critical. As far as the cold rad hose goes, it does take quite a while for an unloaded engine to warm up. You did not say is the heater hoses were hot or not. Not uncommon to have an air lock which can be removed by loosening up one of the heater hoses. Do this from a cold engine after start up.

Well yes I have no drive, pretty apparent something is not working correctly haha. The heater hoses are the least of my concern but they did eventually warm up, just took a bit longer than I thought.
I'm kind of trying to narrow down what exactly went wrong here, not sure I have it in me to pull the engine out and re-check everything a second time.
To further elaborate, I can shift, I feel the car catching both drive and especially reverse (probably servo or solenoid, kind of slams into reverse on occasion). My inclination is that I messed up somewhere regarding the TC, flex plate, or trans pump, unless there is something else engine related I don't know about that would cause the truck to not accelerate, (electrical?) I'm assuming it's a transmission issue. Just looking for some further input as to any possible cause that would create this issue
Thanks for the reply

EDIT: The engine sounds amazing, better than when I bought it 10 years ago, the "tapping" has significantly subsided after warming up from the initial start, I think I can attribute it to common engine noise, nothing really concerning.

Use ForScan to pull the transmission codes. Since the light is flashing I'm betting it's a electrical connection issue.

I wouldn't do anything until you get the codes for the transmission.

All solenoids off in this transmission is 4th gear, so you could be taking off in 4th which wouldn't pull very well from a stop.

I bet its some kind of a wiring issue, if it was a converter issue or a pump issue you wouldn't have reverse.

Check fuse#37 and all your O2 sensor wiring.

Doesn't SSA have to be working to have reverse?

SO long story short, I couldn't figure it out. I got a tow to a shop I had work done at years ago, quoted $2,500 for a full overhaul in the "most likely scenario". TQ, pump, solenoid, bands ect...
Saw this message, turns out I pulled fuse #37 thinking it was JUST A/C clutch, I have the system emptied so didn't want it going off on accident... You can guess what the problem was. Called him up and told him not to bring it into the garage just yet, let me check one thing, VIOLA!
Going to swallow my pride on this one and admit I am a complete idiot. But that's what this site is for eh?
Anyways $175 for the tow sure beats $2500 for a rebuild (if he was dishonest about the diagnosis, who knows)
Thanks a million, to you (and everyone else) on this site for knowing more than I

Ya, never use the fuse to disable the a/c clutch. JUST SIMPLY UNPLUG THE PLUG AT THE A/C CLUTCH!

Yeah you would think, maybe its being feed through the manual valve, I am not sure.

Dodged that bullet!

By saying it barely moves forward told me you were in a higher gear and most likely had no power. Glad you were able to catch it before they pulled it out.
