That makes me wonder if it's not got a pump pressure problem, or maybe boost valve problem in the pump.

It worked fine before I pulled the motor out of the truck it was in that's why I'm so upset with the whole thing

So since you fired the new motor back up the trans is acting like an ass? Something has to be adjusted wrong or something. Or it's one hell of a coincidence.

Actually I had to change one he original to another transmissio I'm a parts truck I wan I'm a parts truck I want drove and and the transmission seem to drive fine I didn't have any problems until I came home from work in Fresno up the Hill like I said before I think it got hot and I'm really lost in and I'm really lost in fed up

So further investigation I found the trans fluid is foamy it has set for almost a week and is still foamy so I think the next step is to change fluid and filter and test and also after driving the truck at my house with 4lo in gauged the front wheels are not locking up and the front drive line is not spinning even with the front hubs locked up so now I think I need to replace the transfer case and check the front hubs to make sure they work like they are supposed to what do u all think I should do with this damn nightmare I call a truck

If they are auto hubs, pull them apart and clean N grease them. I replaced mine with manual Warn hubs.

They are warn manual locking hubs

Well, You strike me as a guy who does not throw in the towel, despite what you say when you are pissed off, and in the heat of the moment.
I say: Its paid for, and once all this **** is taken care of, it will be a reliable vehicle that you can haul the Fam around in, and enjoy tinkering with. I tell ya, I feel your pain. Mine is stuck up in Arcata right now because my pump seal blew, but I really want to fix it, and get it back, even though my wife has been talking about Trading my car in after its paid off, for a newer crew cab pickup.

I'm not that kinda guy I'm just sick of all the BS that keeps coming up with this thing I'm about to put it back on non op and just tear it apart and fix everything that can go bad and then try this mess again lol

Is the motor that you are using with this tranny original with a 700r4? If not the geometry of the tv cable arm would be wrong.

Yes, its correct. Its TBI/700r4 He just swapped out a bad engine.

The following information will be helpful when servicing a HYDRA-MATIC 4L60 transmission for a "no third or fourth gear" or "slipping in third or fourth gear" condition. Many root causes for these problems have been identified, and more than one cause may exist at the same time. This bulletin covers some causes that may not be obvious when doing a normal repair procedure.

Service Information:
Before servicing the transmission, check the following:

^ TV Cable Setting -


Make sure the TV cable is set to the correct position. Never adjust the cable to hide a shift complaint or to change performance. This can mask the root cause and damage the transmission.

^ Fluid Level -


GM Powertrain cannot emphasize enough how important fluid level is to transmission performance. Both high and low fluid levels can cause problems.

A low fluid level causes low line pressure. This can burn clutches by not allowing the clutch to apply quickly enough or by not keeping the clutch fully applied.

A high fluid level allows fluid to become foamy when the fluid is churned through the gearsets. Since air is compressible, the foamy fluid does not apply the clutches with as much force as they need.

^ Cooler Flow -


Perform a cooler flow check as outlined in the cooler flush procedure. Cooler lines can be partially blocked so it is important to know that cooler flow is adequate.

During overhaul, look at the following items:^ Filter Neck Seal -


Examine the filter neck seal for evidence of heat set. It the seal doesn't properly seal around the filter, air can get into the pump and cause low line pressure or aerated fluid. Replace the seal if you suspect it doesn't fit properly.

1.Check oil level.
2.Vacuum modulator defective.
3.Modulator valve sticking.
4.Strainer assembly plugged or leaking at neck
5.Pump assembly regulator or boost valve sticking.
6.Leaks from damaged gaskets or cross leaks from porosity of case.
7.Forward and direct clutches burned.

The newer style filter has no retaining clip. It is held in position only by the interference fit between the suction neck/o-ring/valve body. See part no. 70 in the dwg below.

From TSB 88-T-53:\\

A new design THM 700-R4 transmission fluid filter and filter seal. The new design transmission filter is a wider filter that has a felt element in place of the screen element and a shorter filter neck. The filter also has a molded body that locates over the valve body bolts, thus eliminating the need for the filter retainer clip. The new design filter seal is a wider compression type seal that fits snug in its bore.



When servicing any 1982 through 1987 THM 700-R4 transmission (built prior to Julian date 187), use the previous design transmission filter and seal until current service stock is depleted. When using the new design filter and seal on any 1982 through 1987 THM 700-R4 transmission (built prior to Julian date 187), the filter retaining clip (reference parts book Illustration No. 87) is not needed and should be discarded.NOTICE: Care should be taken when installing the new design filter and filter seal. The filter seal is a compression type seal and will fit snug in its bore. Damage to the filter neck could result if the filter is installed incorrectly.


To correctly install the filter and seal, coat the seal with petroleum jelly or Automatic Transmission Fluid and with the seal over the filter neck, insert the filter into its bore in the pump assembly. With the palm of your hand gently push on the filter until it seats.
