I fought a lot of problems after I got my rebuilt transmission put back in. It would randomly shift into second going down the highway and I thought there might be something wrong with the transmission. but it turns out it was my PCM once I swapped it the issue went away, but I was still having trouble with the lock up hunting while I was driving it would go in and out of lock up a lot. Turned out to be the brake switch, even though the brake switch wasn’t adjusted enough to let the lights turn on when i just touched the brake pedal, there is another switch inside of the brake light switch that ran the lock up and that was Hair trigger, i re-adjusted the brake switch that went away. It’s crazy how unrelated things that don’t set off any sort of a malfunction light can cause you nothing but trouble and there’s really nothing wrong with the transmission.
Yep, very true...Lot's of sensors/switches directly impact the transmission's performance, function and behavior and can have you chasing your tail trying to figure out which ones at times. Thanks for sharing!
Thanks a lot, from Bangkok, I have one of 700R4 on my G20 5.7 van and one of 4L60E one piece case from junk yard, your VDO very useful for me, THANKS again,,,,,
not to mention, I added an external cooler in addition to the radiator cooler and it turns up at the factory shop manual for the Corvette shows the fluid flow backwards through the radiator so I hooked up my cooler wrong i found that out that accidentally too
Nick. Good info. On the hard 1-2 shift. Page 86 of the atsg manual number 372 and 371. In the valve body will also cause a hard shift. All they have to do is hang and it a hard shift. Also, I have had several that still shifted hard after a rebuild. Those ended up with a pcm (eco) as the cure.
Yep, PCM is becoming more of a frequent flyer when it comes to transmission problems, especially in the 90s units as those computers begin to age into disrepair. This trans is back in the vehicle and it's back on the road, no more harsh 1-2 shift (yay!) Thanks, Larry.
Hey it's Josh again. So my bell housing bolts stripped (2 of them) I got the transmission apart without damaging the pump. My question is how can I get it back in with it tearing the O ring on the pump. Thanks
Hi Josh, if you can get the pump w/o-ring installed back into the transmission w/out taking the bell off, please let me know how you did it. I tried once in the same situation and couldn't get it back in...I ended up drilling through the bell housing perpendicular to the bell-case bolts, shearing them in half to get the bell off...Then I weld-repaired the bell housing at those locations.
Hi Dalton...If you're asking about the backstory on the previous rebuild, I learned from the customer that the previous owner had it rebuilt by a shop about 15 years ago. Thank you for watching!

You're welcome, man - glad it was helpful for you...Thank you for watching!
Great video, I have a 95 Corvette with a 4L60E thanks for sharing a differences!
You're welcome, Yeller95Vette and thank you for watching!
Truly amazing how large the filter is on this trans... Get my Honda Accord uses a little tiny one the size of a fuel...
Yes, the Honda trans filters are tiny, haha. Thank you for watching!

Awesome info
Thanks, HMG!

Thank for all information I do watch ur videos. I am getting ready to start on a transmission .
Thank you, Bobby! Appreciate the support. What transmission will you be rebuilding?
@@nickstransmissions i was planning on a 4l60, I think that what I have in my 1994 chevy.. but not sure yet.
Sounds good...If your 1994 chevy is a 1/2 ton 1500 series truck or passenger car, chances are you have a 4L60E.

A new half inch Drill bit. Will drill the heads off the bell housing to case bolts. vice grips will usually then remove the bolts from the case.
@@larryschaum6280 thanks
Possible OEM warranty repair that lasted a long time?
